a pair of circular pipes exists, running in parallel.

I wish to use them as tracks for a small railcar.

where to buy wheels, whose "tread" surface is a semi-circle of the
right size to fit over the pipes? very low speeds in this cargo
application, friction-caused efficiencies should not be an issue.

Or must they be made up by a shop on a custom order?


Always amazes me that I can think up at least three simple things that
I would have included right off to assist in an answer ,rather than a
huge long thread, when asking for help in any "original post" asking
for aid or information.

Where are you located, roughly?

What size is the existing "rail", and is it straight and level, or
curved, or ?????, and what span between centres?

What load capacity?

Used Indoor or out, or both or combined or ????

And -- does the wheel need to drive the carriage along the rail,
or just roll freely?

My first suggestion in the latter case would be to find pulleys
for rope or cable of the same diameter, and use those as wheels.

Enjoy,
