Re: Train Build Axle
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.
(PS: Don't ask me about me other hobby ... there's steam, oil and fire involved.)
The only thing more dangerous than a software engineer with a soldering iron
or a hardware engineer with a compiler is a liberal-arts major with either.
