This refers to activity mode.
Paths over a single track section don't work in one direction. AI trains over such path don't appear or appear on a shorter path.
In the other direction it's OK.
Here a test route (default D9 and consist "1 Dash.con" needed)

There are three activities: Testoffsets1.act, Testoffsets2.act, Testoffsets3.act. In all three activities the player train appears on a short track. After 30 seconds an AI train appears on the nearby track and should run up to almost the end of such track.
In first activity the AI train appears, but disappears after few meters.
In second activity the AI train does not appear at all.
In third activity (opposite direction) the AI train run is regular.

I found out this some years ago and then forgot it (also because such paths are rare). Now charland stumbled into that. I believe (but am not sure) that the problem arises within method public TCRoutePath(AIPath aiPath, int orgDir, float thisTrainLength, Signals orgSignals, int trainNumber, UserSettings settings) in Train.cs.
Unfortunately I don't fully understand the logic of such method, and therefore wasn't able to remove the bug.

Problem is already explained here.

For timetable mode, it is corrected by adding the following test in CheckEndOfRoutePositionTT (in TTTrain.cs) :

            // never return end of route if train has not moved
            if (endOfRoute && DistanceTravelledM < 0.1) endOfRoute = false;

There are now so many differences between timetable and activity mode that I no longer work on code which applies to activities only.

should correct the problem.
In a first phase I'll insert it in the OR NewYear MG version.

Inserted in OR NewYear MG rev. 27.

Morning,

I've been making activities for the FJ&Gv2 for the last few weeks, all start inside and engine house, and the path is just 25 feet long on a single piece of track. As soon as the activity opens one of the first things i do is to go into manual mode and I'll be switching cars for the duration of the activity. Never had a problem with this, is this the same thing you are talking about?

Paul :-)

If the path is for the player train and you switch to manual mode just after activity start you won't see the problem. But here http://www.elvastowe...ils-ai-traffic/ you got the problem for the non appearing AI train.

I was doing the same procedure when my AI traffic wasn't spawning on the isolated south mainline until I added a node and joined it to the rest of the track. But yes, if I don't go into Manual I will not be able to change the switch behind my player train to get on the main track.
