Description
The LNER P2s were among Sir Nigel Gresley's greatest engineering accomplishments. Seven were built from May 1934 to 1936 at Doncaster, numbered 2001 to 2006 and were used on the sleeper trains from Edinburgh to Aberdeen. They were extensively used for testing more mechanical advancements, such as the Caprotti valve gear. However, all of the P2s were rebuilt as 4-6-2s and reclassified as A2/2 by Edward Thompson from 1944-45. None were preserved, but a new one is under construction by the same company who built Tornado, number 2007 Prince of Wales, and its construction is well underway.It comes with two versions, Caprotti valve gear and Walshaerts gear as well.Β

Why would Thompson do such things to Gresleyβs creations?

Gresley, as good as he was, was in his engineering prime during an era when style took priority over function. World War II was hard on everybody and there wasn't a need for purely express engines during a war and mixed traffic engines were needed to carry all sorts of stuff for the war effort.Β

Debatable. True he did value style, but just as much as form. I mean, the V2's were called "The Engines that Won the War" by LNER men. Also relating back to Thompson, almost everything he did to Gresley's creations ended up being worse. The A2/1's (built from what was supposed to be the last four V2's), A2/2's, the dreaded A1/1, the K5 and K1/1 weren't any better than Gresely's designs. They might've been easier to maintain, but they were comparatively poor performers. The P2's could've easily worked traffic in WWII. With the same size drivers as a V2, they would've been the most powerful mixed-traffic engines
