Fine locomotive, but this new motor is quite a bit longer than the 3 or 5 pole type with brushes. And so this causes the motor to stick out prominently from the rear of the cabin as seen here: Here's the same Class C from circa 2000/2001 with the old traditional motor with brushes: For those in the know, is there any technical reason why a brushless motor of similar power would need to be longer and/or larger?

This is the best they could do given the form factor requirements. In design methodology, there is price, performance and form factor. You can't have them all. :D
