Around 1905, a replacement locomotive was considered and W G Bagnall were asked for a design. This was similar to the Lewins design, but more conventional. A saddle tank was used and conventional cylinders with connecting rods to the axle. The power cylinders were however mounted inside the frames and the Bagnall-Price valvgear and slide valves mounted outside. This new locomotive was never constructed, although Bagnalls did instead build two new boilers for the existing locomotives. Both survived the closure of the mine, but were scrapped in 1935, six years afterwards.
