this speeder was most probably designed by
O. (Olly) W. Smith
he used 3-axle trucks for maximum adhesion on the tramway rails. In detail, the trucks looked like this: https://www.flickr.com/photos/51227209@N03/22078046335/in/photostream/
He also built a rail tractor – a twelve wheel drive machine - which worked from 1954 to 1974 on various trams at Mamaku between the forests and the old G. A. Gamman & Co. saw mill, now closed.

If you want to make wooden wheels how taking a spool of thread and cutting the spool itself in half. Many tread spools are made of wood and the edge of the spool would provide the flange. Would have to be radio controlled; maybe a challenge for Woodie?
They used wheel treads wider than normal to allow for operation on wooden rails, too. The flanges, being of normal depth, look shallower in comparison to the wide tread. Wooden wheels were not used on tractors. Have a look at 1982 operations.
