12049 - Class 11 Shunter

12049 - Class 11 Shunter

Status: Operational

The Class 11 shunter as it became classified by British Railways, was the forerunner of the standard BR shunting engine (the Class 08). 106 class 11s were built between 1945 and 1952, by the LMS and latterly British Railways, and they differ slightly from the Class 08 in that they have smaller wheels 48 1/2" in diameter (08 = 54), and also other minor differences.

Built to replace ageing tank engines on yard shunting duties or local loose coupled goods trains the class 11s were never equipped with vacuum train brakes. Their inability to operate fully fitted trains and their non standard nature eventually saw BR decide to withdraw the whole class around 1970, with many locomotives passing into industries such as the National Coal Board etc.

The original 12049 was purchased by DAY Aggregates at Brentford, South West London, and used to shunt their internal sidings. Sadly 12049 was damaged beyond repair by a fire at Ropley in 2010, and has subsequently been replaced by sister 12082 from Barrow Hill and numbered as 12049.

Service History:

12082 was built at Derby Works in November 1950 and initially allocated to Carlisle Kingmoor shed (68A).  She moved around between Kingmoor, Carlisle Upperby, Speke Junction and Toton sheds before moving to Crewe Diesel Depot (5A) on 10/12/66.  Her final allocation for British Rail was to Llandudno Junction (6G) on 15/08/70, staying there until being withdrawn from service on 03/10/71.

From this point onwards 12082 worked in industrial service for the NCB and latterly the Harry Needle Railway Company, before moving to the Mid Hants Railway in 2010.
