A superb design 75029 on the North Yorks Moors Railway

Much of the actual design work of the standards

was down to CS Cocks who was chief draughtsman

at Derby.  

 

 

Of course Robin Riddles (himself an ex Chief Draughtsman)

had over all control and stated the specifications required.

However the designs of the standards was very much a

team effort. Indeed it was largely Riddles who as Chief

Draughtsman under Stanier was responsible

for the design of the Duchesses.

 

So we can see a clear train of progression in the

culmination of the BR team and the superb job

they did. Of course it was Preservationists who

completed the research and development

of the Duke of Gloucester and the

Caprotti valve gear
