PlayStation Wheel Slip Issue

I’m probably doing something wrong but when I in SPG get a sd40 or gp38 In service creator I can’t pull the 40 car options. I put automatic brake switch in and generator field on and everything you do normally and I still get wheel slip when putting the throttle up

 

Have you tried using sand? Just a thought, it might help.

 

Did you forget about the MU-2A valve?

 

Thank you. I always wondered what that was for

 

Sometimes, even when you've followed all the procedures, including for MU/DPU, it still takes a fair amount of skill and patience to start the train.
