Our Class 25 P4 Test Build. Apart from the fitting of our sprung bogie kit, no additional detailing work has been done on this locomotive. Ultrascale wheels were used in the conversion.

Bogie subframe assembly.

Bogie subframe with wheelsets and primary springs in position. The Bachmann final drive gears and bearings are fitted to the axles inboard of the kit’s main axle bearings.

Bogie bolster. The weight of the loco is taken on the flat ‘shoulders’ of the bolster. The optional cosmetic etches representing the bolster end detail have been fitted.

Bolster attached to subframe by secondary suspension, with cosmetic moulded sideframes and brake detail clipped into place. The transverse secondary springs and their seats can be seen in the centre of the bogie.

Drive units: unmodified on left, modified to fit sprung bogie on right.

Bolster and sideframes removed, and drive unit clipped into place over the Bachmann axle bearings. The inner worm bearing is retained by a 14BA screw; this may be augmented by a fold-up etch (shown below).

Bolster refitted over drive unit.

Cosmetic sideframes refitted. The sideframes retain the continuous primary springs.

Similar to above, this view also shows the etched retainer for the inner worm bearing on the drive unit.
