I thought it might be interesting to have a thread on maybe unknown facts about locomotives.
At the moment I am reading a book about William Stroudley from the LBSCR by HJ Campbell Cornwall and it is full of details. Stroudley was something of a perfectionist.
Recently one of the members (sorry cannot remember who) was asking about spring rates and loads to maximise load on the driving wheels but still to follow the track and not roll or bounce.
On page 131 Campbell Cornwall writes:
The springs of the centre axle were made more elastic than those of the leading and trailing axles, since Stroudley wanted the engine to move with the freedom of a four wheeled vehicle.
In engines carried entirely on laminated springs, the increased elasticity was provided by making the springs of the centre axle 6 inches longer than those of the other two axles, though all were of the same breadth and depth."
He did the same on six wheeled tenders.
I am sure we all read railway books and find little titbits of fascinating engineering...
All best
Chris.
