Drop in wheels

Easy to install drop-in wheels for converting N gauge ready to run locomotives to 2mm track/wheel standards. These are designed as replacement axles for the N-gauge items, and include control bosses on the rear of the wheels to limit side-play movement. The range covers Bachmann-Farish though some may be suitable for Dapol items. The fully assembled axle consists of steel wheels, insulated axles, brass gear wheel.

Scale Diameters of Unpowered lead wheels in Farish 40/44/45/46.

Prototype specifications for the 1-Co-Co-1 BR designs had 3ft unpowered wheels and 3ft9in powered. So, prototype scale diameters would be 6mm and 7.5mm respectively. But, Farish' bogie design is not to scale, the supplied N wheels are 6.3 and 6.85 respectively. Having decided to recommend scale (7.5mm) driving wheels, if a scale undriven wheel (6.0mm) is fitted the wheel will hover above the track. So, the recommended "drop-in" solution is to accept a compromise on the lead wheel and fit 7.0mm. A scale solution requires modification to the Farish bogies to make the undriven wheel ride lower; this may be possible, but hasn't been tested.
