The PRESTWIN twin silo powder wagon was a standard design for British Railways introduced from 1960 and used until the early 1980s.

The intial version, Diagram 274, was designed to run on a BR standard 17' 6", 10' wheelbase chassis. A revised design to Diagram 277 lowered the silos by 9" and ran on a 19' 6", 12' wheebase chassis.

This model comprises one bodyshell of each design. Both will fit a Peco NR121 10 foot Steel-type chassis, but the Diagram 277 type should ideally be mounted on a 12 foot wheel-base, 19' 6" chassis.

Basic ladders are included but these could be replaced by brass equivalents. 2mm decals covering both versions are available from Railtec & Cambridge Custom Transfers and Fox Transfers.
