 The opening of Northern United colliery in 1935 produced new instructions for working the Churchway section.Loaded trains were limited to 40 ten-ton wagons or equivalent (soon amended to 35) throughout down to Bullo, while upgoing empties were limited to 23 as far as Bilson, and 15 on the Churchway branch.They were to be propelled up to the colliery from Bilson, with a brake van leading, the open end at the head, and the guard warning anyone on the line by means of a horn.
