I recently picked a couple of Bachmann GP38-2s and they are very nice locomotives, too bad the Bachmann GP40 and GP50 are not up to the same standard.
I have a gp 40 and the drive mechanism is the same identical as the gp 38 -2 and the gp 50.
I meant the shell detailing.
Understandable since the gp 38-2 is of new tooling for the shell. The gp 40 and 50 are old tooling from the 80's or even earlier.
The GP 38-2 is my go to Locomotive. I suggest the Sound Value model if you run DCC. Very smooth running.
