The company continued producing a variety of small industrial and shunting engines at their factory located between Fishponds and Kingswood in Bristol. They became specialists in the field, with very precise specifications and standardisation of parts. The largest engine was an built in 1931 for the Christmas Island Phosphate Company. The works were served by a branch line starting just south west of Kingswood junction on the Midland line and ran for about in a generally eastward direction. It also served some collieries in the Speedwell area. The only evidence remaining of this line is a bridge abutment on Whitefield Road.
