Non-revenue

On Mondays and Tuesdays, the day's mileage was increased to 195½ by a trip from Lewes to Berwick and back. This additional mileage provided the only instance of a non-revenue journey, as the "motor" returned empty from Berwick to Lewes.

The second strategy is to develop specific care and maintenance rules that will need to be strictly followed by the system operator - including the use of specialised machines to clear the permanent way of snowfall, to de-ice the rail grooves and the running of non-revenue services at night to prevent ice formation on the OCL [overhead contact lines].
