Mixed consist of mostly free rolling trucks ,so it runs quite well without struggling.

PS: I kinda wrote off bothering with a single motor F3 of any sort, unless I had two power units. Now I'm wondering if maybe they're made of tougher stuff than I thought, or if it's just more to do with what kind of trucks your cars of choice are rolling on (postwar staple/bar end, vs postwar AAR/Archbar, vs MPC needle point, vs modern diecast needle point)
