#0-4-2

Their first form was an 0-4-2T - with a short coupled wheelbase and and exceedingly long one overall. They displayed a marked reluctance to remain on the rails and were later modified...

Into 0-4-4Ts, with short-wheelbase rear bogies - this did little to aid matters and the class were still apt to sway alarmingly at speed - they were in this form used to work West Country expresses after the end of Broad Gauge and were the cause of a bad accident.

They were then rebuilt again - back to front! As 4-4-0 tender engines they at once became far more attractive as well as more stable - they continued in their work for many more years, reformed characters - they lasted into the 30s, with several receiving larger, tapered boilers and superheaters - while this was an obvious improvement on power it was however the end of their good looks:

In 1910 she was sold to T.W. Ward (A scrap dealer but apparently also involved in the general trade of locomotives), who passed her on to the Shropshire & Montgomeryshire Railway. They rebuilt her (or, had her rebuilt, by Bagnall's of Stafford) in 1911, whence she reappeared as an 0-4-2 - curiously, the centre wheel-arch was left in situ, although the original driving wheels were discarded. This leaves her with non-matching centre wheels, the others are the original Mansells. A 'cab' was added in this rebuild.

She worked on the SMR's passenger services for some time - six passengers could be accommodated in a second enclosed space, added later, which was essentially in her bunker. Passengers tended to complain of the smoke and soot from the chimney, so a single coach was provided - A wooden bodied vehicle on four wheels. This was rebodyed on the same underframe at one point, or else a whole new coach was built to replace the first - sources differ.

In WW2 the SMR was taken over by the War Department, (it served several armaments factories) and in this course of ownership Gazelle was used on line examination trips, inspecting for signs of sabotage, and 'at times' used to convey ammunition. In 1945 she was left at Kinnerley, by the pond and on a siding open to the elements. She had lost her chimney cap at one point, and a crude replacement was fitted. She was also slightly injured by a collision with a W.D. Dean Goods, several of which were provided for the line by the W.D.. In 1950, the line was ceeded into BR Western Region stock - the surviving SMR engines, three ex-LNW Coal Tanks and one Gazelle - were promptly withdrawn. The 0-6-2Ts were cut up at once; however Gazelle was preserved - first at Longmoor and later on various sites under care of the Science Museum and later the NRM. She eventually wound up in Tenterden, and resides in the Col. Stephens museum, on public display, in an enclosed space out of the weather.
