Shock absorbing wagons were first built by the pre-nationalisation railway companies
and British Railways continued to build them to its own designs, as represented by
this kit. Certain fragile goods such as glass and bricks were susceptible to damage
during shunting. The wagon body was connected to the chassis by means of springs
on the outside of the solebars thus absorbing more of the 'shock' of rough shunting
than just the buffers.
The kit consists of a pair of plastic sprues which make up the floor, sides and ends,
as well as the vacuum cylinder, and the trapezoid shapes for the sheet rail. The
sheet rail itself is formed from a piece of brass wire (included) and can be modelled
in the 'up' position or the 'down' position. Pre-cut pieces of plastic strip are
included to fill the chassis over the coupling and to represent the cover over the
spring on the solebar. The model rides on the proven Peco NR-121 10ft WB Chassis
(steel type solebars) which requires slight modification.
The kit can be purchased with transfers to suit either the 1948-1964 period (early
bauxite) or the later post-1964 period (late bauxite) or without transfers at all.
The tooling for this kit has now been donated to The N Gauge Societyand is available
as a twin pack to build the Shock open and the Shock Van.
