175mm wheel base. 100mm dia wheels. 4 no. sealed ball race bearings - (around £1.50 each if the unlikely event they would ever need to be replaced). Motors can be removed without having to split the wheel sets.

These bogies are short wheel base versions. This allows the loco to easily corner around 8ft radius curves.

Each axle box is independently sprung offering an unbelievably smooth ride even on our rough old track.

The removal of the cranks and Delrin axle boxes allows for a reduced maintenance worry. Looking forward to an open track as this engine promises to be a bit of a speed demon. No cranks to worry or throw about.

Available in kit form. Additional fee for wheel set assembly - wheels pressed onto axles, fitting of motor mounts and nylon drive gear. See Hercules prices.
