Axles on Trackmater 1/Plarail Engines

Does anyone know what types of Axles engines like Thomas and Percy use?

Plarail and TM1 Engines use these type of axles (Fisher price models mostly have the Axle attached to the chassis).

I have photos of the axles seen on the Plarail C12 50 (KF-01) and the soon to be discontinued JR 8620 Hitoyoshi #58654 (S-51).

I'll probably attach Paxton's wheels to the axle i'll be buying and buy 3D Printed siderods so I won't have to harvest them from dead engines.

I'm talking about the front wheels of the engine.

I wonder if they an be bought on eBay or Amazon.
