Andrew the Tank Locomotive

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

Andrew the Tank Locomotive

Postby Nevadablue » Sun Jul 13, 2014 2:36 am

So, I got tired of messing about in the itchulation and sheet rock dust and decided to get cleaned up and at least START working on something more fun.

That something is a little tank locomotive. It is an HO loco now, will become a Gn15. The name comes from my good friend who gave me the little machine. Locomotives typically have names, so this one is Andrew!

The poor little thing didn't have a motor and the axle frame was broken off and bent. It is white metal so I'll just cut it off and make a new frame. I will re-use the steam cylinders and the block they mount on as well as the front 'bumper'. That part of the casting is solid and looks good. I'll make the new frame attach with screws probably.

I dug in my parts boxes and came up with a small motor and a worm gear that matches the gear on the locomotive axle. I'll have to drill out the gear for a press fit on the motor shaft. The shaft is long enough so I can support the outboard end of it in a bearing in the new frame. Should work out well.

note: for scale, that worm gear is about 1/2" long.

Thanks Roger. This won't go fast, nothing I do any more goes fast. We are in the middle of summer and the middle of a room addition. I needed a break from the sweaty work so I started this one.
I think the motor/axle frame will be a chunk of aluminum, milled to fit the components. There was a large lead weight in the front of the loco and my hope is that the motor will fit in there after I figure out the frame issues. It is a cute little loco body, worth saving, IMO. :)

Prototype in 1912 http://www.northeast.railfan.net/images/bo99s.jpg
And in Baltimore in 1949 http://www.northeast.railfan.net/images/bo98s.jpg
97 in 1949 http://www.northeast.railfan.net/images/bo97s.jpg
I have read B&O had at last these three, 97, 98 and 99, for working tight places in the Baltimore docks.

looks a bit like the old Rivarossi(Mehano model). I have a couple of the bodies somewhere having used chassis for another project.

That sounds about right. They were last in the Fell's point area working on city streets.

The Pennsylvania RR also had a couple into the '50's in the Jersey City area in equally tight quarters.

It seems anybody who wanted to do a micro layout back them had one, including me for a Gum Stump & Snowshoe effort I did in college. Varney rings a bell.

They called it the little joe.

Both roads replaced them with odd Buckwalter solid rubber tired units around 1955?
