In this video from a couple of years ago, former P2 Engineering Director David Elliott provides a fascinating tour of the three-cylinder monobloc he designed for the locomotive, incorporating modern engineering improvements to optimise performance and efficiency.
David also designed the P2’s unique valve gear, with both systems developed with one ambition: to make No. 2007 the most powerful steam locomotive in the UK.
Sadly, David didn’t live to see his work completed, but his engineering legacy lives on as the P2 takes shape at Darlington Locomotive Works.
Today, the focus is on bringing his valve gear design to life. Find out more at a1steam.com/p2valvegear.
With the monobloc for No. 2007 nearly finished, David Elliot gives ...
