Just south of Nuneaton station, a temporary speed restriction of was in place for a distance of just over a mile because of a track remodelling scheme. The warning board was placed at the standard 'service braking distance' of a mile and a quarter before the restriction. This board should have been illuminated, but was not. The driver claimed that he assumed it meant the restriction had been lifted and did not need to slow the train. It was not until he saw the correctly illuminated 'commencement board' at the start of the restriction that he realized it was still in place, but by then it was too late.
