Please help me identify this locomotive

Recently bought this loco that has me stumped. Got it at an auction and the box was Athearn and the hand written label said it was a GP7. But as I usually do, I like to positively ID my trains and this one is proving difficult.

I can’t find any Rio Grandes with the road number 5103. It has a nice Mashima engine made in Japan. But who made the locomotive and what model is it? Anyone want to take a stab at it?

Well its definetly a Rio Grande GP 7. I was able to find out information about the particular engine here: http://www.drgw.net/info/GP7.

As for brand, i’m not sure. That motor can be bought after-market so it could be any brand.

greediron,

Looking at the handrails I am thinking it is a Front Range Gp7 body, frame and trucks that is repowered with and aftermarket repowering kit (maybe A-Line).

Thank you. I guess that is a good start. It is DCC with that plug going into the circuit board, correct?

Some more detail, to remove the body, I have to unscrew the coupler boxes. I haven’t seen that before, but haven’t dealt with many newer trains, so that could just be a new thing.

I did see the Road # on a Proto2000, but that looks different and has different engine.

It looks like this one.

I am still in awe at what can be found on the internet.

Yes, that is the one. Thanks.

Yup… It is definately a locomotive.

I’ll agree with Dave, it’s a Front Range.

It’s definitely a Front Range. The primary giveaways are the cab windows, which are too small.

Are you sure? It looks like a car to me…

Looks like a portable emergency genset with railroad wheels and a weather-resistant operator’s cab. The latter is handy where the weather runs to monsoons and/or blizzards.
