Just picked up one of these railtrucks and figured I'd offer a quick evaluation.
Out of the box, it is a beautifully detailed model. They even have molded engine details on the electric motor under the hood to help disguise what it really is.
There is a small exhaust pipe running from the motor to just behind the left rear wheel, and the drive shaft is the real thing.
Paint and finish, while slightly "toy-like", is very well done. A little weathering, and it would be top-notch. Add some aftermarket castings like a bell, toolbox, rope, junk, and it will look at home on any end-of-the-line shortline railroad.
Downsides?
only one I noticed is that the power from the track is picked up by the rear wheels, and the front truck. It may seem like a lot, but the front truck connects to the rest of the electrical system by means of small, delicate, wipers. On my model, these do not appear to be making contact with the underside of the frame. The truck spits-n-sputters and doesn't run at all well. If I tilt the body about 30 degrees starboard, it runs better, but not perfect.
Hopefully after work today I will have time to sit down and tinker with it. I'm sure just bending the wipers up so they contact the body more firmly is all it needs. As I just got it last night, I didn't have too much time to play.
I will also have pictures then, for those interested.
And, for the price, I don't mind a little tinkering to get the power pickup correct. A local store has it for close to what Micro-Mark is selling them for, and I don't pay for shipping.
