I mainly use TMR17 and have hardly any issues with the actual trains other then the time out bug which will now be addressed thanks to Tony, what are your issues with it as a train sim ?
I've not tried TMR17 yet apart from downloading sum model routes, As for my issue's my main one being how to create content for a hobby i love like i said above it is near on impossible with the current guidelines. One only has to read the forums to find out the various problems that need addressing, Which is why i said i wish they'd just get one nice working stable version of the game THEN address the extra's sum would like to see added.
