Trip optimizer has been integrated into some PTC equipped engines on the UP. The only time I've had an engine so equipped was before it was active and after the order came out to not use EMS until further notice. I believe they may be trying to intigrate LEADER into PTC also, but I've not seen any UP engines equipped. The PTC display seems to be closer to Trip Optimizer than LEADER in some respects. That's a pity since the LEADER display had better detail than T-O. That's the only good thing I can say about LEADER.

-Don (Random stuff, mostly about trains - what else? http://blerfblog.blogspot.com/)
PTC shows other tracks. It does not show other trains on any track. The track authorized to use will show green or yellow. Green is track with no restrictions. Yellow is speed restricted track due to either signals less than clear or temporary speed restrictions. Equipped PTC track not authorized on shows as red. Non-equipped entrance tracks show as gray. In these gray zones, PTC can be initialized and become active before occupying the PTC track.
One nice thing for us is seeing if we're being held. Information from dispatchers is sometimes non-existant. Some are better than others at letting you know what's going on. Sometimes they are too busy, and sometimes they aren't. Knowing you are going to be held helps plan where to stop when your train only fits one or two places. PTC also allows to see when stopped where no signal exists, when you have been cleared up and can start moving again.
blue streak 1On multi track sections and single tracks with sidings does PC show other trains on other tracks ? Being able to see 6 miles ahead good engineers can control their trains to sometimes prevent coming to a stop for a meet ?
There alread is too much dispatching from the control stand of locomotives. If the REAL Dispatcher wants a train to hold back for a meet - They will notify the train.
blue streak 1If PTC can show multi tracks can PTC show a train on another track has gone into emergency ? The extra seconds of warning might prevent a train from colliding with a derailed train fouling its track ?
My understanding is that PTC displays only preview the track the train is actually operating on. Should a derailment of a train on another track happen, if as is most likely end up affecting the PTC train's track - track circuits on the PTC train's will probably show 'occupied' as the track gets torn up and thereby drop signal on that track.
Never too old to have a happy childhood!

Murphy SidingThe link above looks to be a nice PR piece that suggests that BNSF has PTC working everywhere they are required to. Curiously, there are about 3 segments of track shown with PTC that are isolated from other tracks with PTC equipment. That doesn't make a lot of sense. Are the other railroads as *complete* on the PTC equipment as BNSF says they are on their road? Does PTC equipment from one railroad work on the others?

I suspect that the railroad between the unlinked segments is trackage rights that BNSF has over other carriers who are responsible for their own installation of PTC.
PTC as being installed on the Class 1 carriers is designed for interopratability between carriers. What Amtrak has installed on the NEC does not conform to the PTC that the Class 1 carriers have designed and built.

tree68 Murphy Siding What's the logic behind that? Once the head end passes out of the speed restricted zone the train can speed back up? If the town mothers and fathers are worried about trains "flying" through town, it's the head end they're worried about. The EOT could be doing 80 by the time it gets there - that's not what's going to hit Granny.

I think if those town mothers and fathers are worried about Granny, they are SOL. (Unless the railroad wants to be a good neighbor and abides by a city imposed speed limit.) I believe municipal placed speed limits on trains aren't enforcable. Pre-empted by Federal jurisdiction.

Everyone seems to like it. It lets you see six miles ahead. There are a few things that could be better, but has PTC evolves those changes may happen. Jeff PS. I once ran across a link to the BNSF's pocket reference guide, which is almost the same as ours. (Which is what one would expect since we're all running the same system.)

Murphy SidingWhat's the logic behind that? Once the head end passes out of the speed restricted zone the train can speed back up?
We have a "head end only" at the platform where we pick up canoes. Besides the close clearance, there is the possibility that there will be someone around the platform (although we generally know that), so it gives us a little more cushion.
With our short trains (especially the locals), even if you knock off the brakes as you pass the platform, the speed won't be that high when the EOT goes by.

Yes. Those kind of restrictions are there for operating considerations rather than track conditions.
My end of the railroad doesn't currently have any head end only restrictions. The other end does. I'll have to ask someone who works that way about it. I would guess as soon as the leading edge left the restricted area, the maximum speed display would change from the head end restriction to the next higher allowed speed. Similar to the way it removes the restricted speed hash box when the leading edge reaches the point restricted speed is no longer required.
Unless the programmers never thought about the possibility of head end only restrictions, other than restricted speed.

Under certain circumstances, the position of hand thrown switches need to be confirmed. Other than that, PTC is just another tool to help run the train. It would be better if you could see your entire train on the map display, but you can't have everything. On the map display, only the first 7000 feet or so is displayed. One has to watch the maximum speed allowed display to know when the train has cleared a restriction on trains longer than that. All the other EMS displays showed the entire train, so you could see when you cleared. With PTC you have to take into account that you can't always use the map display to know when you're clear. Jeff

zardoz Murphy Siding tree68 That does raise an interesting sidelight, though - my personal GPS apps usually display the speed limit. How far are we from getting a ticket because an onboard GPS in our personal vehicles sends information to an enforcement authority advising that we've exceeded the speed limit? It would be very easy to make a condition of getting a driver's license or licensing a vehicle that your speed could be monitored as such... Or a component of your insurance coverage. If authorities were really interested in speed control, the travel time between each toll could be used to deduce the vehicle speed; it would be an easy way to enforce traffic laws in a similar way as states that use roadside cameras to nab speeders. They could just mail a speeding ticket the the vehicle owner.

@Murphysiding: My brother has a device in his car now that reports his driving habits to the insurance company in order for him to get cheaper insurance.
@Zardoz: i remember being on a toll road across northern Indiana in the 1950's and there were people parked alongside the road just before a toll booth... Dad said they had been speeding and were letting the clock catch up to them so they would not get a speeding ticket at the next toll booth!

jeffhergert We must report all PTC initiated braking events. If it's from a glitch or other unforseen cause, no problem for the engineer. If you just run your train up to the point, without taking any action, where PTC intiates braking it becomes a train handling incident. I believe it's going to be handled as a critical incident for disciplinary action. Jeff

Some toll roads (like in Illinois) have a 'speed pass' type system where you can pass through tolls without stopping due to a transponder in the car that is read by roadside readers. Use of such devices in 'encouraged' by the toll fare set at roughly 50% of what you pay if you stop and use cash.

Murphy SidingWhat does the engineer or dispatcher do differently with PTC?
My impression is that with PTC, the engineer simply has to comply with displayed restrictions (speed, restricting signals/situations).
On a trip with no special situations, and assuming that the engineer knows and complies with all existing restrictions, I would opine that PTC just becomes another display on the console.
If PTC completely replaces signals, though, it will become very important, and subject to constant monitoring. Even with moving blocks.
This could be a problem, since the PTC display, as shown in the video, is much more complex than cab signals, which I believe simply show aspects. Thus it will take more than a glance to resolve what you're seeing and convert it to usable information.
Just like driving - if you stay within the speed limit and obey stop signs/lights and other traffic regulations, you don't get a ticket.
tree68 jeffhergert We must report all PTC initiated braking events. What I was kind of wondering is whether that information will see the light of day - will a railroad, at any point, be willing to share with the public that PTC initiated penalty braking X times, potentially preventing Y collisions, etc. Even if this was insulated from the individuals and the railroads (ie, a blanket report from the Feds) it could serve to justify the tremendous expense of installing the system. OTOH, if collisions and other incidents continue to occur at a similar rate, it would seem to be something of a condemnation of the effort.

I think that information would be a something of a hot potato. As such, it would be used by corporate PR/Spin departments to make it look however they wanted it to appear. With the right amount of creative writing, you could make the data look like a big financial drain on the poor stockholders and ask for some government concessions to make things right. On the other hand, you could prove that your railroad is much safer now- “just look at the number of crashes we could have had!”

zugmann tree68 I wonder if there is/will be a built in reporting of penalty applications - incidents where PTC may well have prevented an incident. Yes. If the PTC has to stop your train (going into the red zone is the term, I guess), it must be reported and then will be handled as appropriate.
