Talk:R. B. Longridge and Company

From Wikipedia, the free encyclopedia

Sources differ on how many Crampton locomotives Longridge built for the Great Northern Railway. Number 200 was later converted from a 4-2-0 to a conventional 2-2-2. There were nine similar 2-2-2 locomotives numbered 91-99 and it is uncertain whether these were built as 2-2-2 or whether they were converted from 4-2-0 like number 200.

I haven't followed this all through, and I hope I'm not teaching my granny to suck eggs. But don't confuse the Stephenson Long Boiler with the Crampton. After the first few models, the Long Boiler was a 4-2-0 to give greater stability, like the "Great A". The distinguishing feature of the Crampton was that the driving wheels were behind the firebox.

I agree with your definition of a Crampton but I think we are talking about different things. GNR 200 was built as a Crampton and converted to a non-Crampton. Did GNR 91-99 receive the same treatment or were they built as non-Cramptons? Biscuittin (talk) 16:53, 8 December 2007 (UTC)

I only have Lowe for a reference. He says ten Cramptons were built for the GNR and "they" were subsequently converted to 2-2-2 by Archibald Sturrock. I only wanted to post a note somewhere, as I had noticed a number of amendments about Cramptons in various articles, and saw a trap for the less knowledgable.
