What lacks pulling power? Spectrum Standard, or Proto 2000 steam? The 2-8-4s sure do. But I'm happy with my 0-8-0s.

Stay away from the early releases of the Proto 0-8-0. These do not have the tender pickups and stall easily at turnouts.
Just what everyone needs a switcher that has to stay out of the yards as there are too many turnouts there. Looks good though.
