The crossing has no barriers, but is the only crossing on the SVR protected by flashing lights displayed to road traffic. The warning lights are operated automatically by track circuits and treadles, with a white light displayed to the train to indicate that they are operating correctly. Modern-style warning boards consisting of a black cross on a white square background are positioned on the approach to the crossing in both directions.
Northwood only became an ‘open’ crossing in July 1980. Before then a hand signalman was required to be present during operations.<ref>SVR News</ref>
