As the subject, really - I want some more locos, the N2 and the 8F both look good, both use 5-pole motors so should run smoothly at low speeds - any downsides? I don't care about super-detail, I just like an engine to run nicely and have good traction without spending all day cleaning wheels (mentioning no tender-drive A4 Pacifics).
