Despite the provision of mitigation measures (see [8.38 & 8.39]), a further SPAD incident occurred at signal T22 at Norwood Junction on 20 October 2000. Following this, the original countdown markers were replaced by new ones having blue and white edging and stating the signal number [8.57]. The original line reminder sign alongside the signal head (see [8.39]) was replaced by one with a white background and blue and white edging [8.58].

Position light shunting signal E961 at Southampton Maritime Freightliner Terminal was a multi-SPAD signal. To assist drivers in locating the signal, double-sided signs reading "Beware E961" were positioned adjacent to it, on both sides of the line [8.60]. A similar pair of signs was installed adjacent to signal E940 at Millbrook Freightliner Terminal.

Signal W187 on the Down Slow line at Wimbledon is the first signal beyond the flyover that carries the Up Slow line over the Fast lines. Approaching from the north, the Down lines are separated by the Up Slow, but beyond the flyover they run adjacent to each other. On occasions, drivers running on the Down Slow had been misled into reading the Down Fast signal adjacent to W187. In May 2001, as a short term remedy, line reminder signs with a letter "S" [8.61] were erected on the approach to signal W187 and adjacent to the signal itself.

In 2002, a series of six countdown markers were provided on the approach to signal S49 at Dore. Some of the markers are located inside Bradway Tunnel.

Some signal reminder boards installed in the East Anglia area of the Eastern Region from 2002 have included the words "falling gradient" on their supplementary signs to assist drivers who are braking to stop at the signals concerned [8.63].

Late in 2002, the Scotland Zone reversed its decision of three years earlier, and changed most of its signal reminder boards so that they no longer had a yellow background (see [8.40 & 8.41]), reverting instead to the original colours [8.66 & 8.67].
