This is driving me insane, I have watched Matt and others on youtube and still cannot figure out what I am doing wrong, I have followed all the steps/instructions and have started the loco successfully and moved down the line and connected to the wagons-disabled cab and switched cab and I cannot get the loco and wagons to move forward, the square gear indicator in the speedo remains a red colour, any help appreciated.
I think you put the reverser in Neutral on the shutdown cab, but it should be in Off. I made the same mistake.
