 CNW 6000:

Neat thread...got another trick for us to switch?  Otherwise I may (if you're ok with it) present one I've seen locally here.

 

 

All yours bud...

Okey dokey...

This situation is one where there are two industries within close proximity to each other, but the points face opposite directions.  Both industries don't always get served on the same day...but sometimes they do.  Today is one of those days.  There is a small yard (for intermediate storage basically - the older cars are on Track 4, newest on Track 1) near the two industries but it sits on the other side of a CTC mainline.  The local that works here must also set themselves up to be able to switch a third industry further down (photo right) the line...but not near the yard.  After that industry is served they head back home (photo left) when they're done.  This is a job that usually takes its full 12.  The tracks leading to the third industry don't have room for any extra cars (from the first two industries) so they'll have to be left in the yard.  The siding isn't used by any 'through' freights and there are grade crossings on either end of the yard that aren't supposed to be blocked for very long.  One handbrake is required per track on the right (photo) end of each siding and at each spot for the industries.

Setup:
Your train has just arrived from photo left.  As stated both jobs are worked today...plus the third off map.  You must:
-Industry A: Pull Empty cars, place the remaining cars on their correct spots based on spot number, place two cars at the empty spots and get Empty cars ready to go back with you at the end of the night.
-Industry B: Pull Empty cars, place new cars on spot from yard, cycling new/old (look at note).  Empty cars go back with you at the end of the night after the third industry.
-Industry C (off map):  They take three cars in and send three cars out.  Take the three "oldest" Z cars with you and you're coming back with three empties.

At the end of serving all three places you should have all empties going back with you.

Diagram below.

Yes, this is real.  Good luck.

Lots of room to play there.  How many cars do tracks 1-4 hold? Which ends are the handbrakes on?  How many cars can you fit between Industry A and B switches?

It's been fun.  But it isn't much fun anymore.   Signing off for now.

When I tried to view the image at full size, I got nothing but the home page of Photobucket.  Mayhaps it is not flagged for PUBLIC viewing?

Which of the 3 "Y" cars is to go into the "Y" spot?  Leaving it up to the crew might lead to a single car sitting on the siding until the 40 year rule causes it to be scrapped.

Which 3 are the "oldest" of  the 7 "Z'" cars?

How long can you tie up the CTC Main storing cars temporarily on it?

Which cars go to industry "C"... just any at all at my whim?

Given the total lack of detail given in some of the answers to the previous puzzle, I will switch this job this way...

1) Arrange the cars in the order I need and put them in the proper place.  There!  One step!  What do I win?  :-)

What the hell, I'll take a stab at her. 

 

Better open the image to follow along. 

1. Cut away light.

2. Go to Industry A.

3. pull it all.

4. Leave one empty + "2" on the main. 

5. Slam "4" back on the siding. 

6.  put the empty that you are holding onto against the other one on the main.  No sense holding onto it.

7. Run lite on the main to the west (left) end.

8. couple to the rear of the train you brought.

9. drag it all out and go into the west end of the yard.

10.  go into track 1

11. grab car "3".

12. Set car "1" and "3" to the ladder. 

13. Toss your inbound "x,z, y" to track 1.  They will stay there.

14. couple to "1 and 3", reach into track 4 and grab the old "y" car.

15. double all that to track 3.

16.    shift out the x car towards 2, and put one z car to 4, and one back to 3.  That will leave you with 3    old  z cars together for that industry later.

17. Grab the "x" you sidetracked and back to the main. put the "y" and "x" to the main. 

18. go into the siding, holding on to 1 and 3. 

19 slam 3 into industry a.

20. reach out, grab 2, and put 1 and 2 in industry a.

21. done with spotting A.

22. reverse and grab empties out of industry B.

23. back to the main, and shove back to pick up the y and x cars you put there earlier.

24. run into the siding from the east end, back up and spot the two loads into B.

25. Done with B.

26.  Now you are holding to 2 empties west of you and have 2 empties on the main east of the siding. 

27. leave the 2 empties from B on the siding.

28. run light to the main and pick up the 2 empties that you left there from A.

29. Reverse into the east end of the yard for track 4.

30. Reverse again, and pull the Zs out the east end (saves you from throwing the switches on the west end).

31.  Go west on the main, with the Zs on the west end, engine in the middle, and empties on the east end. put your 2 empties on the siding from the west end, against the 2 you pulled from industry B. That way the 4 empties are together for a simple pickup later.

32. Back to the main.  You now have 3 Z cars and the engines. 

33.  Go shift Z.

34. On the way back, scoop up the 4 empties you left on the siding.

35.  When you grab the cars on the siding, tie the train down and wait for the re-crew.

Not the prettiest... but it will get the cars to the right spots.

 

It's been fun.  But it isn't much fun anymore.   Signing off for now.

Track 1 holds about 15 cars, T2 holds about 12, T3 holds about 10 cars and T4 holds 8.  Handbrakes are on the photo-right side.  You can usually get about 6 cars between switches.

 On instances when only A or B gets switched they can usually fly back home and tie up with about 15 minutes to spare.

Charles - as I explained in the note above the diagram...the "the older cars are on Track 4, newest on Track 1".  Only one Y car needs to go there - the oldest available.  That age guideline applies to the "C" industry as well.  The dispatcher typically will not let you leave cars on the main, even during the windows they let you out on the main.  Sorry if that wasn't clear in my original explanation.  I also don't normally use photobucket as the "share" feature isn't as easy as Flickr.

If you can't leave cars on the main (even for short moves), then you'd do what I did above, but just drag the extra cars with you.  Makes it a pain in the butt, but still do-able.

Gotcha.  Your rendition was pretty close, for the record.

Another day, another puzzle.

 

Same industry as before: 

 

Here is the new situation:

 

There's 2 empty (MT) cars below the pit, and another empty on the pit. 3 loads behind the pit.  You have 2 new loads head out on your train, plus a bunch of loads for other industries behind them.  How best to switch this customer in the fewest number of moves?  You have full use of the main for the night.  The lead for the industry is actually on a pretty good grade, so take that in account, i.e. it's probably not the best idea (or even possible)  to try to shove the WHOLE train up there.

 

Bit easier than the other one I posted.

 

PS.  I actually enjoy switching this industry.  Gives me a little bit of a challenge.

It's been fun.  But it isn't much fun anymore.   Signing off for now.

Where in the train do the empties get blocked?

I'll just slap them on the head end for now.

1.  Cut off light, grab everything on the spur.

2.  Pull down, cutting car 3 on the spur.

3.  Grab car 2 from main, standing cut.  This avoids airing up the whole train when unnecessary.  Also it is a lot faster than moving ahead one car for cut.

4.  Grab car 3 from spur.  If grades and rules allow, roll it out.

5.  Grab car 4 from main, standing cut.

6. Shove to spot. 

7.  If empties go somewhere else in train, cut off on spur, and feather in as needed.  Otherwise, tie on, airtest, hiball.

My favorite switch move: Cut head pin , engines back off to the house, tie on hand brakes, run to the parking lot.
