i have the exact problem with my gp35 legacy im using a zw from the 1950s and found out if i slowly turn on track power the loco starts right up but doesnt move. I turned off power and turned it back on fast and it works. I am no expert on modern tech but my theory is the loco is not seeing 18volts right away and the low volts at start up isnt enough to start the program just my observation
