The sidings at the wharf were laid in a triangle. The coal wagons descended the incline under braking relying on gravity and accumulated momentum to carry them to the sidings where they were connected to an endless rope kept in motion by a stationary steam engine in the centre of the triangle. The endless rope went around three wheels at the corners of the triangle. One was sited on the Erewash Canal's aqueduct which spanned the Erewash River, a second was under the bridge which carried the Eastwood Colliery's branch line over the Shipley line and the third was alongside Eastwood Lock. Using this mechanism the colliery wagons were brought alongside the wharf and could be emptied directly into waiting narrowboats.
