I came across some model freight trains of my late father. And could use some assistance identifying the loco in the pic. It runs!. I'm still learning the wheel nomenclature.

Is this an 0-6-0?

The middle two wheels don't drive but not sure if that is just a model difference or if original was built same way? 

Name?

As always, thanks in advance for review and comment. This is always a very helpful forum.

I've got a HO scale Manuta 2-6-6-2T that I'm hoping to use as the basis for an On30 conversion.  However, it has a rather unusual problem.  When I put the plastic chassis on it, the locomotive runs smoothly.  But as soon as I put any weight on it (such as the body), it starts to perform poorly.  It'll limp along the track, and the motor will even stall at some points.

Well, its officially been (almost) a month since I started this series, and to celebrate that achievement, we have moved on from smaller locomotives (for the time being) to focus on the great articulate locomotives of the world.  I know what you're all thinking.  "Finally!  About time we get to show something B

Please see attached pics.

Can someone help me identify vintage...and likely required source voltage. I'm thinking it's 17-24V   AC, but applied that with no response. Likely DOA but if any troubleshooting suggestions, would appreciate. Manually, One set of wheels turns freely (with resistance). The other turns, then locks up.

appreciate the review/input. Thx!
