Also, if it has tmcc then why ERR?
The factory TMCC is designed for Pullmore motors and has 32 speed steps and no cruise control.
Electric railroad's Cruise Commander works on DC motors, will give 100 speed steps, and will maintain constant speed around curves and up/down grades and over places where the track power is not as strong.
