LNER Peppercorn A2 Class steam locomotives – Sole Survivor

Powerful and fast, the Peppercorn A2s were some of the best and last Pacifics designed by the LNER and form the topic for this week’s Sole Survivor.

Once we look at their short working lives, we will then explore the preservation history of the last class member left.

The order for 15 engines which became the Peppercorn A2s was originally for the Thompson-designed A2/3 class. Thompson used many different designs for locomotive components compared to Gresley, these can be seen both visually and on drawings.

Even before the A2/3s entered service, many people doubted their design. When Peppercorn became Chief Mechanical Engineer (CME) in July 1946, the other 15 engines ordered were halted while Peppercorn and his drawing office team modified the design. By December 1947, construction was well advanced with building the new class. LNER Peppercorn A2 Class steam locomotives – Sole Survivor
