Great Northern (IE) class QGT
Ireland 1904 2 produced
In 1904, Charles Clifford, superintendent of the Irish Great Northern, had two 0-6-2T tank locomotives built for shunting work in the Belfast freight yard. They came from Robert Stephenson & Co. and were given the numbers 98 and 99. The cylinders were on the inside and drove the second driving axle. Ultimately only 98 remained permanently in Belfast, while 99 was later moved to Dublin. They each received a new superheated boiler in 1932 and 1935, respectively.
