The Cooke 0-8-2T were two 0-8-2 steam tank locomotives built in 1899 for the Port Talbot Railway (PTR), South Wales. Their PTR numbers were 20 and 21 and they became Great Western Railway (GWR) nos. 1378 and 1379.

The PTR obtained tenders from six British and three American companies and the winning tender was from the Cooke Locomotive and Machine Works of Paterson, New Jersey, USA. Cooke's London agents were Thomas W. Ford & Company of Palace Chambers, 9 Bridge Street, Westminster.

The locomotives had bar frames (as was usual American practice) but, otherwise, they were of quite "British" appearance. Both were fitted with new boilers at the GWR's Swindon Works in 1908.

Performance

The locomotives were required to haul a train of 300 tons up a bank of 1 in 40 at 12 mph and 800 tons up a bank of 1 in 75 at 12 mph. Initially, the locomotives failed to meet these targets but, after some modifications, the required performances were achieved.

On coal trains, one 0-8-2T replaced a pair of 0-6-2Ts and this resulted in a significant saving in fuel and labour costs. Coal consumption was 65 lb per mile for a 0-8-2T compared with 94 lb per mile for a pair of 0-6-2Ts.

Further locomotives

The PTR had an option to buy three or five more locomotives from Cooke to the same design but it chose not to exercise this option. Instead, it bought three 0-8-2T from Sharp Stewart of Glasgow in 1901.

The two classes are easy to distinguish in photographs because, on the Cooke locomotives, the cylinders were dead horizontal and drove on the second axle, while on the Sharp Stewart locomotives they were slightly inclined and drove on the third axle.
