Lionel Lionchief GP7 vs RS3?

I don't own ether one, but the recall I recall hearing the recall was about the traction tires.

FYI, IT also depends on how realistic you want them to look. The Rs3 has an incorrect molded in GP7 type of fuel tank where as the GP7/9 is more correct in appearance with a metal frame and a correct GP7/9 looking fuel tank.

Oh, I just remembered the RS3 was used for passenger service, not many GP7 were, none are coming to mind at the moment. If that means anything.

If you're talking about the Lionchief Plus GP7 it is considered to be above the starter set diesels.  It has vertical can motors with fly wheels, smoke, cruise control and sounds.  The sounds are reported to be good not great.  It also can be controlled with the transformer or the included remote.  Detail is good not great.

The starter set is a good value if you can use the track and transformer.  The diesel will probably have small horizontal can motors in the trucks.  Sounds could be included or could be just a horn.  If it is a Lionchief set it will only work with the included remote.

I have a Lionchief Plus Mikado and really like it.  Some don't like that each engine requires it's own remote.
