Train just disappears?

[autodctr]

This has happened 3 times now....all on the same layout. 3 different trains though. One of them just disappears! No wreck or derailment or anything that I can find. The driver will still appear in the driver's list, but he will not be assigned to a train. This is happening only to trains when they are moving. I have a total of 17 trains moving and only one will disappear.

Any thoughts?

Specs: Ryzen 7 2700, RTX 2070, 16g RAM. Running completely on a SSD. Trains 114800.

Sounds familiar and not always just one, sometimes 2-3, but unfortunately I've never been able to reproduce it hence little point in raising a report. I have 35-40 trains running at any one time and although its happened a handful of time there seems no set interval, no particular train or location although I am suspicious of Windows updating in the background. It may be my imagination but since I've disconnect my games PC from the network, connecting it only about one a month for updates and the occasional asset download I don't recall an issue. Peter

The train may very well have derailed, but you didn't notice. I have actually had the same thing occur, but didn't notice the derailment. What I did notice was one of the drivers sitting in the driver list without a train even though that driver was assigned a train before. One day I caught the quick-moving notice in the status messages. "Consist xxx has derailed" with xxx being a number. I was lucky to catch the message in time and I searched for consist xxx and found it. The culprit causing the derailments in my case is a portal which still gives me fits even after the "bug fix" for that.

I use no portals, no AI. This was a train running on the same track as 11 other trains. The track is a little over 200 miles long. One train leaves the station at a certain speed. Next train leaves a minute or two later going 2-3 MPH slower. 3rd train leaves and speed set to 2-3 MPH slower than previous train. So and and so forth until last train leaves. Train leave yard safely and track switch is thrown so that all the trains will just keep on going round and round. Speed differential between first train and last train will be about 25MPH. On a 200 mile track, that will take quite awhile for the fastest to catch up to the slowest. That is why I do it that way. Then I can lean back in my chair and watch trains run. This afternoon, the last train left the station about 30 minutes after the first one. So, there was no way that the first one caught up that quickly. NONE of the trains had gotten to the next track switch which is at 120 miles in. In settings, it was set for no derailments. The train just disappeared. Lastly, it was the very last train to leave the station that disappeared. And I know that it left safely because I was watching it so that I could turn the track switch back to the proper direction. There is no way that it derailed.

To be sure of that, watch that train and bring up the message log and keep an eye on that. It could be the last train encounters something somewhere that causes the derailment. The problem is this doesn't always happen and if it does occur it occurs randomly making the problem elusive.

My example of encountering the portal issue is just one of the many causes of a derailment. There are many including an AI driver flipping a switch under its mate at just the right moment. When an AI driver waits at a signal for access to a junction, they don't just wait and will constantly flip the junction lever as if they're playing Rock, Paper Scissor. While annoying in most cases, they can catch another driver off guard and cause a derailment. I have witnessed that on a very compact trolley route I run with about a dozen AI driver making their circuits.

The other thing that can cause a derailment is a junction-controller. The issue here is the AI doesn't "see" the junction as being controlled by the junction controller and will flip the switch on their own. In this instance, they can catch another driver that is crossing over the switches at just the wrong moment and derail. On my trolley route I mentioned, I used to use those and ended up with trolleys being split apart with only the front end running while the remaining parts derailed on the side. There's also an issue with very long passenger and freight cars where they will get caught across junctions and end up being derailed by another AI train.

I use no AI at all....never have. In fact, I wouldn't know where to start if I wanted to use it. To me, Trainz is replacing what I used to have when I was much younger: a bunch of trains running around and just enjoying watching them run.

I'm not sure from the OP whether the trains are disappearing while the session is running or that when you load a saved session the train is no longer visable. It sound like yours are disappearing while a session is running. In my case I'm sure the train was there when I saving the session but it had disappeared with symptoms similar to yours (shows on the menu but when you click on the train it is not there but it can be located somewhere on the map as a bunch of cars piled on each other in the middle of no where). Here is/was my problem and I posted this a year ago (January, 2021). I assume the if this is still happening after the "update" to build 114800 that the problem has not beeen fixed.

One final comment. I have used TRS19 very little since mid-2020 because of the disappearing consist problem reported a year or so ago. I have not seen anything that indicated this has been diagnosed or corrected. In my case, the disappearing consists were comprised mostly of Build 3.3 (TS2010) content that I moved over to TRS19. These kuids still use the IM files. I don't know if the IM files or lower build numbers have anything to do with the disappearing consists but I thought I'd mention that. Unless or until that problem is resolved I see no reason to continue using TRS19. In my case I run sessions and save them and come back later and run some more and save again. Let us say I have saved 10 times with 10 separate sessions. When I open session 10 and find my consist out in a field somewhere looking like it was stomped into the ground vertically by the Jolly Green Giant I am not happy. I go back to an earlier session and find my consist is missing there as well all the way back to and including the original session. All I can do is delete all saved sessions, edit the original session, and start over. I cannot trust TRS19.

 

[autodctr]

Yes....this is happening during a session. However, I can find no pile of cars anywhere. The driver still appears in the list of drivers but it says that he is not assigned to any train. The train is gone w/o a trace.

I reported this ages ago and the issue was confirmed and passed on by the QA Team to the Developers.

For some reason the session loses its positioning and the assets end up circling around the World Origin.

In one instance, I was able to grab the various rail cars and drag them back to a nearby track then move them back into position. In other instances, I could not do that and ended up running Delete Missing Assets to clear them up and repopulate the session again, and then another time I got smart and restored to an earlier backup.

For 3 days, no problems. But today, I have tried 4 times to get all the trains moving but I lose at least one train before I am 20 minutes in. This is crazy. And you want to sell me Trz2022 when 2019 still has so many issues??

 

[autodctr]

More to the story: I went back and tried 3 more times, all with the same result. Except this time, it was always the same train! So, when I took a closer look at it, it was disappearing when it entered a tunnel. Looking into the tunnel, there was no track! The portal or entrance was still there, but no track inside of the tunnel. I replaced that piece of track and everything, so far, is operating properly. Understand that NOTHING changed from last night when it operated fine. What caused the track to disappear? Why are other trains disappearing without tunnels?

 

[JCitron]

Yay! That's good to hear/read.

The reason for the track just disappearing is the track could be faulty, open for edit, or perhaps on a different layer that's hidden.

 

[autodctr]

I don't use layers for anything. I have been using the same track forever and have never had an issue before. This time, I know what caused the disappearing train. The 7 or 10 times previously, no idea: different track, different locos every time. Aggravating.

I suggest you send a bug report in with a link to the route and content required. Include full operating instructions. QA will take a look.
