I've got a good selection of hi-rail locomotives, mostly MTH's Premier line; and I've got a couple of MTH's scale wheels units.
My latest 2-rail locomotive, a CNW Dash 9, has curling or tilted looking pilots/stairs(from the side view). The screwed on pilot, doesn't make a nice seamless connection, to the main chassis. There are gaps(at least 1/16th or greater)... looking from the side or underneath. Not a nice, tight mating of parts. The space between the chassis and the trucks makes the unit look, stilt-like. When I asked my dealer what he thought of this particular model, the space between the trucks and chassis, didn't impress him. Those holes in the front pilot, for the the ditch light wires, aren't real looking. That has a toyish look.
Guys, on the 2-rail forum and 3RS, seemed to fawn over these scale wheels offerings. So far, I'm not that blown away.
This is the 3rd scale wheels locomotive model, that I've had in my hands. My first was a UP SD70ACe; second, a CN ES44DC and the CNW Dash-9. I think the scale wheels units have a somewhat cheap appearance/feel to them. Not what I would consider, the best...
I've got two MTH Premier models in the works, and I'm paying at least an extra $100.00(over the regular list price) for one of them. I cancelled the two 2-rail models, I had on order and got some things a little bit different...
