Cast iron alone is too soft. Chinese cast iron can be even worse than soft, crumbly.
The train wheel would be round but I was thinking of a section of the axle between the wheels. Remember, all you really need is a 6" section of 4" solid rod. Bigger would be better but that would do so make sure your brother knows you're not asking for an entire 20 ft (or whatever length they are) section of track!
