Robert Stephenson & Hawthorn     Works No 7671    S&L No 60 Jupiter 0-6-0ST

This locomotive was built in 1950 by Robert Stephenson & Hawthorn for Stewart & Lloyds steelworks at Corby in Northamptonshire.

Immediately after the Second World War Stewarts & Lloyds began a process of improving the ironstone branches serving the large iron and steel plant at Corby. One outlying ironstone pit at Harringworth was isolated from the main system, and ore from it had to be conveyed over a stretch of the LMSR. To obviate this the company extended their own system of quarry lines to reach Harringworth, and for this long-haul traffic they ordered seven powerful saddle tanks to their own detailed requirements.

This locomotive was one of that batch of seven locomotives (Works Nos 7667-7673) that was delivered to Stewart & Lloyds and became S&L 56-62. This locomotive became S&L No 60.

Two further locomotives (Works Nos 7761 & 8050) were built in 1954 and in 1958 bringing the class total to nine engines.

They became known as Uglies due to their short saddle tanks and larger fireboxes. These give them a somewhat ungainly appearance, but they are a more powerful locomotive than the Hunslet Austerities.

All of the locomotives of this class were withdrawn from service in 1969 when they were replaced by diesel traction. Five of the nine locomotives have since been preserved – Works Nos 7667, 7668, 7671, 7673 and 7761.

The locomotive has been at the Colne Valley Railway for many years and is under restoration there.
