STOP GOING BACKWARDS!!!!!!!!!

AAARGHHH!!! I am so tired of this problem! :(

Here it is: My route that I have been working on for almost seven months is basically a LOOP. I.E., there is absolutely no reason for any of my A.I. drivers to back up.... I have the track all laid perfectly... I have markers indicating just what path the engineers should follow--- but, every once in a while, after one of my coal trains finishes loading, the engineer will REVERSE and begin going BACKWARDS!!!!! ARRGH!!! This makes me SOOO MADDDDD!!!! Is there any way to absolutely STOP an A.I. driver from ever reversing? There's NO NEED for the engineer to ever go in reverse.
 
Well, the AI likes to take the shortest path to an assigned destination, so I can only figure that it's shorter if the AI backs up (even if it's just by an inch).

What I can suggest is using the "Drive via Trackmark" command to make it go to a given trackpoint ahead of it, and then proceed to the destiation. :wave:
 
Sometimes the AI get confused and forgets the path that it took previously. It will attempt to seek a more direct path even if it means backing up several miles. More often, it will reverse to find an open junction, then proceed forward into that junction. I've had trains move backward and forward several times on the same path before they finally decided which way to go. Also, if you have other traffic running, the driver may decide to move out of the way of intersecting traffic until the route is cleared.
 
you didn't save when AI had just finished loading?. It can make them for some unknown reason go into reverse.
 
Make a trackmark at a shorter distance. I have a rather large route and have to put a couple of "drive vias" to get the routing right.
 
Everyone so far is right on. Drive via trackmarks are the best way to solve the problem, especially when your route is a loop. A loop can really confuse the AI sometimes. The AI will ALWAYS try to drive the shortest distance and depending upon what traffic is ahead or the condition of turnouts and signals ahead, I've had AI drivers back up may 2 or three miles before deciding it was okay to drive forward. I really haven't figured out why they do this sometimes, but they do. Whenever they decide to backup, I'll usually take control of the train, drive it through the next junction ahead of the train and give control back to the AI. After doing this, the train usually goes merrily along its way.
A lot of it is just trial and error trying to figure out what's going on.
 
A trick I have learned is to use Track Direction Markers - that effectively stops the AI train going against the traffic flow!

Hi davesnow,
Imediately after the load command give the driver a "stop train" command then a "wait for 5 seconds" command then continue with your other commands. I find this works 99 time out of 100. But having said this, loops can be tricky. Do you also find the driver misses a trackmark first time arround?

Hope this helps,

Coal train? It wouldn't have helper locos at the back would it?

I have recently had all sorts of problems with trains with 'pusher' locos confusing the AI as to which end was the front...

Hi dermmy,

In Trainz you cannot use a pusher sucsessfully except on DMUs or EMUs. If you use two diesel locos I think you will find one is dragging with the wheels not turning, this applies to steam locos as well. You can however use double headers.

Sorry Bill, but I have successful pushers and mid-train helpers in numerous sessions. There are however circumstances (including industry tracks) in which they are problematical. But in general, no probs. Watch for my upcoming Clovis Sub route and associated introductory session....

Andy :)
 
Hi Andy,
Well I have never been able to run a train under AI with a pusher. Even if I drive the pusher up to the rear of the train myself, as soon as the AI takes over the pusher drags it's wheels. Do you have an AI driver in each loco or one driver for the lot?

Cheers,
Bill
p.s.
BTW. Can you tell me how to upload to TRS2006? I can't find it anywhere. I have made a route and a session into CDP files but can't find where to go from there.

Cheers,
Bill

Double units.

When operating multiple steam locomotives, you have to set the regulator, cutoff, and brakes independently for every single locomotive. Does this apply to multiple diesel units as well? I've seen lots of screenshots with double and triple headers, so I think it's okay. Correct me if I'm wrong. My AI trains generally seldom have reversing problems, unless if Alastair missed a switch or something. The offending train would just back up, change the turnout direction and continue. Problems with steep gradients, I guess.
