Someone mentioned in another thread that it really helps to run industry spurs off a branch line so as not to foul the main line.
But, what if you don't have a branch line?
One of my industries is a double ended spur that connects to the main line on either end of the spur. No problem there with dropping off cars at the spur while picking up other cars to return to the yard.
On two other industries, for each industry, I have a single spur line off the main line, but it splits off into a 2-track spur. So, I can drop cars off and pick other cars up without ever having to re-enter the main line.
It is my fourth industry that raises a problem. It is a single track spur off the main line. What do you do in that case if you have cars to be dropped off and cars to be picked up?

richhotrain It is my fourth industry that raises a problem. It is a single track spur off the main line. What do you do in that case if you have cars to be dropped off and cars to be picked up?
Rich,First there is no problem.
What would I do?
The same thing I did when I worked on the railroad.We stopped and switched out cars at the industry just like they do today and will for years to come as long as that industry requires rail service and their are thousands of such industries located along the main lines.
Its ok to foul the main when there is work to perform and did you know there are thousands of small outlaying yards that uses the mainline as a yard lead?
This way why I caution everybody about what they read in layout books,operation books or magazine articles written by so called "experts" that has no real clue of every day railroading.

From a couple of eastern Roads in the "caboose era": Before leaving a location where the local was clear of the main, the conductor would inform the dispatcher (usually not directly, but through a tower operator) of the work to done and the time required until the local could get to the next point where it could clear the main. It was up to the dispatcher when to let the local out on the main. Sometimes the local could sit for a long while if there was a lot of other traffic to run. Usually the local is pretty low on the dispatchers priority list, so it was a good idea for the local crew to pack a big lunch.
If the local couldn't clear the main at an industry, the usual move was to leave everything on the main (not forgetting to flag if necessary) and first go in the spur with the engine and get the pick-ups and hold on to them while spotting the inbounds. That way, when the train is all coupled up and ready to leave, the brakes on the picked-up cars have had some time to charge. (Don't forget the flagman)
By the way, some main line locals on the B&O used to run with a caboose on the rear for the flagman and a caboose right behind the engine for the conductor (and maybe the front brakeman)
DSO17Usually the local is pretty low on the dispatchers priority list, so it was a good idea for the local crew to pack a big lunch.
Actually locals and MOW crews are a thorn in the DS's and (back in the day) tower operator's backside..The operation department don't like 'em either.Some railroads sees 'em as a necessary evil.
Some railroads wasn't above forcing small 1 or 2 car a week industries to trucks and spun off profitable branch lines and some industrial heavy main lines to short lines and regional railroads.
richhotrain Someone mentioned in another thread that it really helps to run industry spurs off a branch line so as not to foul the main line.
Its not really a "branch line", they are talking about a lead parallel to the main, looks like a siding.
You don't have any problem whatsoever. You line is double tracked. You give the local a section of one main, then run the trains around it on the other main.
Why wouldn't you just pick up the cars at the same time you set out?
On two other industries, for each industry, I have a single spur line off the main line, but it splits off into a 2-track spur. So, I can drop cars off and pick other cars up without ever having to re-enter the main line. It is my fourth industry that raises a problem. It is a single track spur off the main line. What do you do in that case if you have cars to be dropped off and cars to be picked up?
If you can set out cars you can pick up cars. You do it all at the same time. You are running a loop. Why even bother turning the train? Run one local clockwise and another local counter clockwise. From the yard back to the yard. It never changes directions.

That is a very good point.
I think not wanting to foul the main is more common in model railroads than real ones simply because space is limited on our layouts and trains come by more frequently, prompting a need to get the switcher out of the way. It may not depict real railroad operations since there is more time to switch them, hopefully.
If Rich only has one industry that requires switching from the main, it may only be a problem if the dispatcher schedules a highballing passenger train to follow the local. .
If the local is a short enough train, is it possible to extend the industry spur enough to park the train on (before the industry, not in front of it)?
Edit: If Rich has a double main all the way around, he could install crossovers at the proper places.

PRR had a local that worked between Terre Haute and E St Louis. It came west on m-w-f and went back east on t-th-sat. They worked all the trailing point industries coming west and the others on the way back the next day. So some cars made a round trip to E St Louis and got set out on the way back.
On rare occasion, they would have a hot car that had to be set out when traveling in the wrong direction and that would require a runaround move. These special moves were usually instigated by some mucky-muck in freight sales or customer service bureau and they would often make the dispatcher scream like a Lutheran farmer.
Part of the problem was even though the PRR was a double tracked road, it was single track from Smithboro to Brownstown Il and prior to the PC merger there was heavy traffic in both directions.

While working on a factory addition in an industrial park in Pleasant Prairie, WI. , I got a chance to watch the UP switch industries that are located right on their main line (former CNW line), as it goes through this industrial park. There was a dead-end spur, right off the main, that was like a "frontage road", that served maybe two or three industries. Some though, were served by a single spur, right off the main. The switch crew often used the main as staging as they moved cars in and out. This is a very busy line, and the switch crew would occasionally have to wait in one of the spurs while a through train used the main. This is a double track main, so that made things a little easier.
Another interesting thing, just north of where we were working, was a huge coal fired power plant, with a constant movement of unit coal trains, all of which, was located on this main line. I was always going to "Google it" and check out the satellite view of the track layout, and see how it connected to the main.
Just my random thoughts,
Mike.

dehusman Why wouldn't you just pick up the cars at the same time you set out?
That's what I would do on the double ended spur.
Pull the cars to be set out into the spur, uncouple, and then push the cars to be picked up out onto the main line, reverse direction of the loco, and pull the picked up cars back to the yard.
richhotrainSomeone mentioned in another thread that it really helps to run industry spurs off a branch line so as not to foul the main line.
That's certainly not true for a large portion of the real railroads, or it's a misuse of the term "branch line". Often, there is a siding paralleling the main to which industry spurs attach (which is not a "branch line", by definition).
But on less-heavily-used secondary mains and true branches, some industry spurs connect directly -- this can even occur occasionally on busier mains, though it is a pain for the dispatcher and crews. In many cases even today, freight crews worked at night to avoid heavier traffic (such as passenger or commuter trains) in the daytime.
Since you have a double-track main (apparently), you may simply have the local trains working between crossovers and route the through traffic around them, as others have pointed out.
Note also that real crews (and efficient modelers) usually pull and spot cars at the same time at a given industry. That happens whether the industry spur is single-ended or double-ended.
As mentioned before, piecing this together from different posts by different people with differing degrees of experience seems much harder than referring to primary sources*. Or best of all, visit an established op session or two -- you'll learn more in a couple of hours than in a couple of months on-line.

Not wanting to foul the main definitely gets more emphasis on model railroads than on the real thing.
One aspect of this that I've noticed is that, especially in club situations, there are those who just don't think that stopping one's train and having to wait for another train to clear up is their idea of fun.
I once had a fellow club member tell me that "If [his] train isn't moving, [he's] not having fun."
I can see that being a common sentiment, but it sure can be a problem on a club layout with several trains running that have to stay out of each other's way...
I guess it depends a bit on which game you're playing.

Mike,I switch a power plant like that in eastern Ky..We stopped on the main,set the handbrake on the caboose and uncouple and pull west of the switch and would back 140-160 cars into the power plant inbound lead and then make our pickup on their outbound lead..We would walk the the lenght of the pickups and connect airhoses,check bleeder valves,release set brake wheels etc..This operation took over a hour since we had to pump the air..
Thankfully the dispacther could use the eastbound main to run trains around us.

Byron, thanks for those comments - - very helpful.
I do have a double main line with a number of crossovers so, as you say, fouling the main line should not be a problem.
I do plan to pull and spot cars at the same time at a given industry, as you and others have suggested.
Adding some crossovers would help, as was mentioned before. The following drawing is the way that I would add them for right-hand running. This would allow other trains to pass while you are working the sidings. You could also use them as a run-around while switching if you needed to.
Elmer.
The above is my opinion, from an active and experienced Model Railroader in N scale and HO since 1961.
(Modeling Freelance, Eastern US, HO scale, in 1962, with NCE DCC for locomotive control and a stand alone LocoNet for block detection and signals.) http://waynes-trains.com/ at home, and N scale at the Club.
Elmer,That also gives the local crew room to work..
If it was a long distance between the crossover switches then one could add a "short" crossover between the crossover switches.Railroads would do this to help shorten the time a local crew would tie up the mains since they wouldn't have a long distance to travel while making a runaround move..
richhotrain dehusman Why wouldn't you just pick up the cars at the same time you set out? That's what I would do on the double ended spur.
Why wouldn't you do it on the single ended spurs? That's how probably 90% of all spurs are switched (technically that's how 100% of all spurs are switched since spurs are single ended tracks). Puick up and set out at the same time from one end.

Dave, that is my question, at least in part.
If the industry spur is a single track right off the main line, how do you both set out and pick up cars in the most efficient manner?
You might not understand what I'm saying.
Your local arrives at a single ended spur, for example, the Public track (team track), at Montchanin, DE. They have one car to set out and one to pick up.
The engine comes off with the spot car (the white reefer):
It reaches in and picks up the the pull car (the PRR Great Southern Despatch boxcar):
The engine pulls it to the main:
And then shoves it back against the train, comes off with the spot car:
Shoves the spot car back to a spot.
Secures the car and comes back out to the main:
The engine shoves back to the train, they get an air test.
Fnally the train departs to the next station they have work.
Single main track.
Worked off the main.
Both set out and picked up at the same time.
It was a train, not just an engine and it had a caboose.
Does that help clarify the mechanics of what a local does? Do you see how just handling two cars consumes many moves and a lot of time (i.e. play value)? On my layout I think I can keep a local busy pulling and spotting 6-9 cars (i.e. 4 in, 4 out) each at 3 locations for an entire 3 hour op session.

Dave,
First of all, I enjoyed that photo sequence. Thanks for that.
I did understand what you were saying, and I do understand the mechanics of what a local does.
What I thought you might be suggesting was a way to set out and drop cars on a single spur without interfering with, or fouling, the main line.
The way you did it in the photo sequence is how I assumed that it had to be done. But it does require the use of the main line. So, to avoid that, I am going to try and make that a 2-track spur.

Why is that a problem? That's how railroad's work.
How will making it a "two track spur" keep you from using the main track? A two track spur would work no differently than a one track spur other than instead of taking cars out of and putting cars into the same track, you take cars out of one track and put them in the other.

Everything you are saying about operations is helpful and informative to me, and I am taking it all in.
But you have to remember, as an operations neophyte, I am like an impressionable young child.
Someone says it is best not to foul the main line with local switching operations, so I decide to take that advice to heart and try to avoid fouling the main line with local switching operations.
So, I start this thread and then come to understand that fouling the main line with local switching is not so bad and real railroads do it all the time. Still, I am intrigued by the prospect of local switching without fouling the main line.
Of my four industries, only one would currently require spotting a car on the main line since it is a single track spur. If I can add another track to the spur, then I can spot the incoming car(s) on the second track while I pick up the outgoing car(s) on the first track. As it turns out, I can add that second track and, in doing so, I can complete the switching operation without ever using the main line until I am ready to have the local re-enter the main line after completing the local switching.
In the final analysis, I am a happy camper because, in the absence of a true branch line, I can conduct local switching operations without fouling the main line.

I know very little about operations, I think if it were me, that's what I would do, but then again I know very little of the subject.

richhotrain Rich, if I can add my thoughts....but I'm no ops expert by any means... Someone says it is best not to foul the main line with local switching operations, so I decide to take that advice to heart and try to avoid fouling the main line with local switching operations. I think the concept of fouling the main mostly applies to large yards where a switcher must take a gawd awful amount of time to make up or break down trains. Inevitably, some train going somewhere will have to stop or the switcher will have to duck into the yard to let it pass. If it is a busy yard and main, the switcher would have to duck into the yard often and the entire railroad would lose efficiency. The railroad would likely find it beneficial to invest in more track, like a drill track separate from the main. On a layout, having to occasionally duck into the yard to avoid a train might be considered challenging. Having to do it over and over again, would likely be considered annoying, so modelers may want to design a separate drill track into the layout. I think what Dave showed in his example is more typical of how a local switches its train. On a model railroad, that local would only be a problem if, for whatever reason, another train was running at the same time along that spot on the layout. If your layout's not that busy, the local should have enough time. But it also wouldn't kill efficiency if just one train had to stop to wait for the local to move on, hopefully to the nearest passing siding. How many trains you got moving in that one spot at the same time? You're a DCC guy right? Of my four industries, only one would currently require spotting a car on the main line since it is a single track spur. If I can add another track to the spur, then I can spot the incoming car(s) on the second track while I pick up the outgoing car(s) on the first track. As it turns out, I can add that second track and, in doing so, I can complete the switching operation without ever using the main line until I am ready to have the local re-enter the main line after completing the local switching. The second spur will need to be long enough to hold the entire train in order to keep it off of the main, right? Building that long of a spur and backing an entire train onto it is probably something a real railroad would want to avoid. However, it would keep the second train on your layout from having to stop.

How busy in is your main line?
Your dispatcher must give "Track and Time" to the local to do its work, thus the next through train cannot leave the terminal or otherwise proceed until the dispatcher gives the track back to him.
If the dispatcher told the LOCAL he could have the mane lion until 1400, then at 1400 his train must be clear and the switches aligned for the main line. AND the dispatcher and other trains will ASSUME that this has happened. If it has not the LOCAL train will have to call the dispatcher with a warning that the track has not been cleared yet. The dispatcher will hold the trains for you but the Superintendent will have your tail in a sling once you get back to your terminal.
To be fair though, the dispatcher will give you the time that you need, but it may not be all in one lump, you may have to clear the main say between 1400 and the time that train 2571 West clear your location, and then you can have the track back until 1600. WATCH THE TRAINS CAREFULLY, Train 2571 might not be the first westbound to pass your location.
Anyway, this is what makes railroading fun, or so they say. The LION, OTOH has his own way of doing things, and while running SIX trains all at once, an inspiration arrived in the head of the LION for implementing AUTOMATIC SIGNALS on his layout. It will probably cost about $200.00 so I will have to get my ducks in order and know what I want to do before I can take it to the Abbot to ask for money.

It just depends on how much money the railroad wants to spend to reduce delays. If you have multiple main tracks then the need for a switching lead or runner, is lessened. You just run the trains on main one while you switch on main two.
As it turns out, I can add that second track and, in doing so, I can complete the switching operation without ever using the main line until I am ready to have the local re-enter the main line after completing the local switching.
Part of it is that I am approaching it from the concept of running a local and you appear to be running a switch engine out to switch one industry at a time.
That's one way to do it and if you're happy great. I would just suggest at some time take the chance and switch like the real railroads do with a train, its really a lot more fun.
Rich,
I am Just getting back into model rairoading so I am not trying to be an expert at this or anything like it. From what I have read it your origional post and the comments I just want to put my 2 cents in to see if it makes sense to you and everyone else.
Fouling the main is not a problem wether it be a branch line rr or a class 1 rr. If you have to do it to do the job then you do it. Where I am I have a shortline across the street that doesnt have to worry about it(Grafton and Upton rr) and CSX which on its main that it shares with the MBTA commuter rail(Owns the main from worcester/framingham to boston) has some industries that are off the main and they have to "foul" top switch it.
With the whole 2 spur industry track is it a large enough customer to warrent it? I know its not always fun to be purerly prototypical but most industries have to pay themselves for the trackage that directly serves them so if they don't get enough frieght in or ship out to warrent having dedicated tracks then they don't. On top of that (depending the era your modeling) most industries around my way that I've gone and checked out usually either just recieve or just ship by rail.
From an operations stand point usuing the main to switch would almost be better, You need to get the local switching done in a certain time frame if not or the locals running behind the crew needs to sit on a siding to wait for oncoming trains to clear. It gives a sense of urgency to the crews working the local on your layout. Also gives the "realistic" if the crew guys are having a bad day the dipatching has to think a little differently and the through train/passenger crews get a mix up to the normal routine. My personal opinion I think it makes for a more interesting session.
Again just my humble opinion and I am by no means an expert, hope my babeling made some sense to you and everyone.

ahhh, I see what you mean.
Thanks for pointing out that difference between running a local and running a switch engine. I am by no means wedded to the concept of a switch engine as opposed to running a local. When you pointed out that difference, that previous photo sequence that you posted made even more sense.
Dave, don't give up on me. I am learning, slowly but surely. I am open to all ideas and operations concepts.
I just hope that this thread, and the other related operations threads, are as interesting and informative to others as they are to me.

How many trains you got moving in that one spot at the same time? You're a DCC guy right?
Yep, it is a DCC powered layout.
A big part of my concern is that I am one of those lone wolf operators.
I run both passenger trains and freight trains on a double main line.
So, while I am performing switching duties, I may have two trains running on each main line track.
Without at least one other operator and without a dispatcher, I am at risk of running trains into one another if I am also fouling the main line with switching operations.
That is in large part why I am expressing concern over this issue and trying to do what I can to keep switch operations separate from main line through trains.

Also gives the "realistic" if the crew guys are having a bad day the dipatching has to think a little differently and the through train/passenger crews get a mix up to the normal routine. My personal opinion I think it makes for a more interesting session.
Kevin, thanks for adding to this discussion. I have to laugh at myself, because I have gone in one day from a single stub end spur to a double track spur and then back again to a single track spur. I just have to sort all of this out and decide what is most important to me in terms of prototypical operations.
richhotrain Without at least one other operator and without a dispatcher, I am at risk of running trains into one another if I am also fouling the main line with switching operations.
While I can fully appreciate your just concerns about having a collision I can't help but ask..
What's so important about running 2 trains at time on the mains?
Why not just one train and your local?
I did that on my N Scale 36" x 80" DC HCD layout and had fun.
