N°E658 photographed at an unkown location during early Southern Railway days.

The X6 class 4-4-0 was an Adams design introduced by Drummond in December 1895 at the same time as the T6 class was being built. Very similar in design the X6s had six inch smaller coupled wheels and correspondingly smaller bogie wheels,to the same measurements as on the T3 class. These locos were the subject of detail changes by Drummond and were the first to be given the abbreviated initials "S. W. R." on the tender with a smooth number plate and devoid of brass beading. Apparently it was Adams' intention to build a class of tweny engines, but Drummond thought otherwise and only ten were constructed. The numbers that might have been used by further X6 engines were taken up by M7s. One of the engines, N°658, was later fitted with a Drummond boiler and was also the last of the Adams 4-4-0 types to remain in service.
