Kit Features
Etched brass fold-up construction.
Steel ‘guitar wire’ springing.
Primary and Secondary springing.
Primary springing by two independent spring beams on each side of each bogie to mimic the sprung equalization beams of the prototype.
Secure fit to locomotive chassis block, using an etched brass pivot frame.
Adjustable ride height using plastic card spacers.
Uses original A1A drive units, with straightforward modifications.
The centre, undriven axles are securely located and weighted.
The original cosmetic bogie sideframes are re-used, suitable fixing surfaces being provided.
The bogies are mounted in the locomotive by etched brass pivot frames secured to the chassis block.
The bolster tops are secured to the pivot frames by a thread-locked brass screw, under a slight
pre-tension to ensure that the bolster swivels freely but without any rocking movement. A plastic card spacer
between the two allows fine control of ride height.
Heljan drive unit, temporarily separated from its undertray, modified to fit sprung bogie. External fixings and clips
are removed, and the slot for the centre, undriven, axle is opened out so that the unit does not interfere with the
movement of that axle. The original pickup strips are glued to the side of the unit, slotted in to
the residual stubs of the sideframe mounting spigots.
Subframe for Lion bogie kit. The four wire beam secondary springs are fitted.
Lion bogie subframe, carried on Ultrascale P4 wheelsets retained by the wire beam primary springs, and
with the bolster secured and supported in place above by the secondary spring beams.
The cosmetic sideframes wrap around the brass subframe with little modification, fixed to the
end stretchers and intermediate outriggers. An alternative outer end stretcher is provided to allow the NEM
coupler pockets to be retained.
The drive unit in place in the subframe. The bolster arches over the drive unit when fitted.
