This was the railway's reason for existence. It charged a fixed rate per ton for taking loaded coal wagons from Tilmanstone Colliery to Shepherdswell (no further) for switching onto the main line and for returning empties. Since the colliery possessed no locomotives, it also performed necessary shunting duties at the mine, including taking coal from the screens to the power station that ran the electric drainage pumps. Tonnage was over 200,000 after 1926. Rates agreed in 1932 were £0.0315 per ton to Shepherdswell, internal shunting at the colliery at £0.0126 per ton, 1,000 tons of free coal per year for railway use and £0.90 per ton over that. In return, the railway had to obtain all its coal from the colliery, and bad quality was to be a problem. The Southern Railway credited the EKLR £0.042 per ton of coal forwarded to them.
