Product Description
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.  


Examples of these wagons can be viewed on Paul Bartlett's Wagon Site, including both designs together.
