1951 was the year of the Standard Steam Locomotive. The Railway Magazine of the time focussed on the development of these locos. Rather than just looking backwards to those days, it is good to listen to and read things from the perspective of the time!

Before i was born. Was this the year of the festival of britain?
First thing I noticed was there is no spec for the 9F.
