    Default Train Build Axle

    I found a wheelchair to use for my train build. The main problem with the motor and axel is it is a solid axle with both wheels attached. I can't figure out how to remove just the motor to use it so I'm thinking of using the whole axel but it is 24" wide. If I use the axle as is the train engine should be around 5' long. Is that too big for a front yard train? I would have to figure out how big to make the curves for it to make a full circuit.

    Should I find a different type of wheelchair to grab the motor from or keep it a very large train.

    Bob:

    A lot depends upon the size of your yard.

    The minimum radius diameters of your curves will be determined not so much by the width of the gauge but by the length of the wheel bases on the locomotive and cars. Short wheelbases mean you can have tighter curves.

    But a 24-inch gauge is still going to mean you're going to need a really, really big yard. A quick consultation with Wikipedia shows the minimum curve on a 2-foot gauge road was 16-foot radius ... if you can't lay out the, ahem, railroad in smaller than a 32-foot wide circle, then you probably should look for a different motor and build a smaller railroad.

    I'm not a ride-on guy ... just a humble 45mm (aka Gauge One; aka G Gauge) steamer, mostly in 1:20.3 but with some other scales as well.

    (For the uninitiated, the cost difference between ride-on and Gauge One is about $20,000 per locomotive.)

    Let's see some photos!!! This sounds cool! My grandfather was an engineer on the Soo line, so I've always had a keen interest in trains!

    Photos of me running engines are few and far between ... but here's a nice page where I make a special guest appearance:

    (I usually make the photos at these types of events, so that's why the text makes reference to people being amazed I ran a locomotive.)

    Those are beautifully machined! How long will they run at one time before needing more water or fuel? What kind of fuel do you use? Charcoal briquette? How often do you guys get together and run your trains? What a great hobby!!!

    Some are built in workshops; some are commercial. Mine is a circa 1970s German locomotive made by a Japanese firm and sold by a German company.

    Virtually all are designed to run out of fuel before water. Some of them have external water tanks and others you can top off while they're under steam pressure. But from operating pressure to end-of-fuel is usually 20-40 minutes.

    Not enough heat in charcoal. Most use butane (think camping stove rather than cigarette lighter); some use alcohol, and a few use real coal.

    It is a great hobby. Here in the Bay Area we usually get together once a month during the spring-winter-fall; folks up your way seem to not get started until May and end up operations in September ;-) ...

    i found that 24 inch is a bit wide but it will work. (if you have the room)
