Hmmm.I did put the GP50 and a GP9 with identical DCC decoders and identical CV values on the track. The end speed is the same but the GP9 is faster in the middle. The trucks of the models do look similar but not the same.
However, my GP50 is an older model not in production anymore (7078). The GP50 at train world has a different road number (9014) and might be still in production. It would make sense to me if Bachmann uses only one truck design on all Geeps and therefor one gear ratio. How about a short question at the Bachmann forum (http://www.bachmanntrains.com/home-usa/b...d,2.0.html)? Mr. Bachmann is answering quite fast.
