Description History
Designed and built during Sir Topham Hatt’s tenure as CME, this loco was the first of three ‘Hatt Class Sevens’. Hatt was able to procure drawings from Swindon for the GWR ‘King’ class through his contacts there, and his drawing office used these to design a 4 cylinder locomotive to pull the heaviest expresses, but with more sure-footedness than a Pacific (after the experiences with No.704).

The first loco was built with Walschaerts valve gear (it is thought that the young Charles Hatt had some say in this), though the second and third had Lentz rotary poppet valve gear.

Construction was contracted to the North British Locomotive Co. due to the success of the ‘Royal Scots’ on the LMS and the new engine, 705 was named ‘Westlin’ after a Sudrian racehorse entered in the Grand National.  It was delivered in the summer of 1929, with classmates No.706 ‘Harold the Black’ and 707 ‘Starstrider’ following in 1930.

Mainly used on express passenger services and boat trains alongside 704 ‘Duke of Gordon’.

In 1961 ‘Westlin’ was in need of major overhaul. It was deemed uneconomical to repair and was withdrawn.
