4mm Coaches
The current range is based on the concepts of 'swing link' suspension. This is how prototype coaches are mounted on their bogies. It means that the body sways about an axis near the roof, instead of rocking on the top of the bogies. Even on dead flat track there is a need for flexibility in the bogie since the wheels are coned, and any sideways movement will cause one wheel to ride up, and the other down. This means that the liklihood of a derailment is increased for a solid chassis - even on level track. Not only should the bogies have this flexibility, but it is required between the bogies as well. However to achieve this it is important that the bogie pivots permit rotation about the vertical axis but only about this axis.

2 Brass channels,and a number of etched crossbeams, and bogie pivot bearing housings enable a simple skeleton framed chassis to be assembled. You may then add all the various batteries, gas tanks, truss rods and brakegear appropriate to the particular coach. The solebars and buffer beam should form part of the body rather than the underframe. These parts will be different for each type of coach.

These simple etchings fold up to provide a frame onto which cosmetic sides may be glued so as to enable bogies to be made up quickly and accurately. The bogies are suspended from swing links that impart that prototypical sway so typical of period coaches. The pivot is a short vertical shaft that ensures a low friction bearing and prevents that unrealistic rocking of toy trains. The axle bearings are located in slots so that the axle and bearings may be dropped into the inverted frame without distorting it. The cosmetic sides are then glued onto the sides of the frame, and lock the bearings into position. The bogies are retained by means of an E-clip in a groove at the top of the steel post. This allows for a quick release of the bogie, once the chassis has been detached. There is a slot beneath the post, through which the wire of an Alex Jackson coupling may be passed. The coupling is fixed to the chassis at a point above the back of the bogie, whilst a wire loop at the front of the bogie will steer the wire to align with the bogie centreline.
