Joyce (works number 7109) was ordered by Croydon Gasworks and gained the number 37 in their fleet. It was given the name Joyce after the daughter of Mr Sandeman, the chairman of Croydon Gas works where it operated for 32 years until 1960.
Apparently, after testing by the LMS, that company ordered two similar machines for shunting on its Somerset & Dorset Joint Railway branches serving the collieries around Radstock, Somerset; these became LMS Nos 7190/1 and BR 47190/1.
The locomotive is unusual in having vertical water-tube boiler supplying transversely mounted cylinders that transmit power to the wheels via gears and chains. Its central section houses a four-inch thick cast-iron water tank to provide ballast as well as hold water.
