With reading thru the forums and alot of people getting stuck on SPG due to not setting up their locomotives correctly, I think 1 or 2 advanced tutorials should be added to the game. One Tutorial would be dedicated to the AC4400 and another for either the SD40-2 or GP38-2. The tutorials would cover things such as cold starting, DPUs, and other things not covered in the basic tutorial.
Sadly couldn't move that loco, and i've followed all the steps from the instruction. Generall every other route is ok but SPG doens't like me. Btw advanced tutorials for all routes would be welcome.
