Anyone know where I can find N scale trackmobile or a start on kit/scratch bashing of one.
That will be a tough one. If you are able to locate a mecanism to power it, I would love to know where you find it. You might look into pager motors - the motor that vibrates it. Gearing and getting power to the trucks will be another challenge. You can do it if you want to tho May the force be with you.
What is it???????????????Pat
small kritter like machine to move single railcars around industry
http://www.trackmobile.com/TM_Models.htm ...many versions and looks. Some great feedback on another board...
It's basically a tractor (like on a payloader) with rail wheels, you could drive it on the road, put it on the rails, lift the road wheels and use to to move cars around.
There was an article in the May 1985 MR about scratch-building a trackmobile in HO. IIRC they used a flea to power it and styrene for the body, and wheels from a tractor kit or something like that for the road wheels. In N scale the motor and gear box would probably cause the biggest problems, those critters are SMALL.
Alcoa runs one, but I never see it while I have a camera

Thanks Guys that really helps the picture just put the icing on cake Jon. I assume the wheels are driven by an electric motor or is it a diesel? And what makes the wheel raise and lower?
Most or all are diesel or gas, I dunno if they are mechanical or electric, but I immagine the wheels are raised and lowered electrically. You might find an answer to that at: www.trackmobile.com/
I think they are diesel/hydraulic. The diesel engine turns a hydraulic pump. The wheels are powered by hydraulic motors, and the wheels are raised and lowered by hydraulic rams.
That makes a lot more sense than diesel electric in a package that small. I wonder if the gas jobbies are electric or hydro. I would doubt gas mechanical, since they need to raise the wheels.
There are a number of them in this area. With a little luck this coming week I can get some more photos for you guys.
Trackmobiles are nothing like diesel-electric locomotives when it comes to how they function. They use a regular industrial transmission and transfer-case to drive the rail wheels. Some of the smaller models just use a straight shaft type axle while the larger ones use heavy duty planetary type axles similar to a front-end loader or other earth moving equipment. The road wheels are hydraulically lowered to allow off-rail travel and are usually driven by an interlocking hub via the rail wheel, although they are sometimes driven by a hydraulic motor at each tire. Trackmobiles come in a wide range of sizes, the smallest being powered by a 4 cyl. gas engine, but, with the use of the unique weight-transfer coupler, it can still move 2 to 3 rail cars (100 ton each). The largest model, the TM5500 has a 400 hp diesel and can move over 50 cars in ideal conditions. I am not at all affiliated with Trackmobile, I'm just a former operator and I've bought and sold some as well.
Here are 3 different models. I have several other pics as well as specs. and dimensions if someone needs them.
