I believe I have been able to reproduce the locomotive stall bug that myself and others have seen.
I have uploaded a .zip file of a simple route and session using all built-in assets.

The task is simple. Using DCC mode, spot each of the 5 tank cars on a separate yard track and return the loco to the starting position. I use the on screen icon to uncouple so do that please. In 24 of 25 times running this session the loco will stall at a random point after uncoupling from the tank car and moving a short distance away. Turning the DCC dial will increase the amount of smoke and noise from the loco but it will not move. If you use the 3 dots to change to Cab Control then you find that all the settings are set correctly and the train starts to move. Stop the loco and then return to DCC mode and you have control again. The bug may repeat again if you choose to continue but it is random at which point it shows up.
It does not appear to matter what order you choose to spot the tank cars or on what track you choose. The bug always appears after uncoupling and the loco moving away even if the loco is still coupled to the other tank cars.
I wanted to keep this as bare bones as possible so I did not include signals or trackmarks but I suspect that this might be the same bug that effects driver commands.
If anyone would like to test my findings please feel free. I created this in the latest version of Trainz Plus build 117669
