Alco held the license for the Gresley conjugated valve gear in the US. Before the UP 4-12-2 there were a few 4-10-2 using the Gresley motion. The...
Looks to be the original 1912 publication. I don't recall it ever being reprinted.
The T1 had 502,200 lb locomotive weight, the rest being the tender. Of that, 279.910 was on the driving wheels. 122.720 on the trailing truck and...
I think there may have been a total of 43 NCB tanks fitted with the Giesl Ejector. The first one was fitted to an Austerity tank in 1959, and the...
The slipping problem was really the downfall of the Duplex design. Even the Q2 anti slip device did not entirely solve the problems, and would not...

And the Highland Rivers of 1915, despite being designed at Cowlairs and sold to St Rollox. Probably the best Scottish 4 6 0

I believe that the valve gear model used at Derby is on display at the Derby industrial museum.
Didn't the NRM in it's currently location officially open on 27/9/1975, 150 years after the opening of the Stockton and Darlington railway? The...
I am always amazed by the 'British is best' approach in the UK. The Pennsylvania Railroad was producing a two cylinder, wide firebox, superheated,...
