At Ipswich, a signal reminder board with the words "check CO799" [8.86] was provided at the exit from the Carriage Sidings, on the approach to shunting signal number CO799. On the approach to London Liverpool Street, one reminder board on the Up Main line applies to the signals on either leg of the divergence ahead (L58 to the left and L56 to the right) [8.87].

Following the opening of the new Edinburgh Park station, temporary "station ahead" signs [8.88] were installed on each rail approach in 2004. Also in 2004, a temporary signal reminder board [8.89] was installed on the approach to a new signal (number SJ40) at Stanley Junction (Scotland Region).

In 2005, two countdown markers were provided on the Up direction approach to Chandler's Ford station (Wessex Route), stating the distance to the station [8.90]. Similar markers, including also a third one at the ¾ mile position, were installed in 2006 on the approaches to Whimple (Down direction) and Earley (Up direction) stations.

In 2006, experimental signs were placed at a distance of one mile on the approaches to Christchurch and Ashford (Middlesex) stations, in the Down direction only, to help prevent station over-runs [8.91].

Drivers run an increased risk of forgetting to stop at a particular station if not every service is booked to call there. Three stations where this applies are Treforest Estate, Romford (Main line platforms only) and Capenhurst. To prompt drivers to think about whether or not their train is booked to call these stations, reminder signs have been provided at the preceding stations in each direction of travel. Signs bearing the name "Treforest Estate" [8.94] are installed at Treforest in the Down direction and at Taffs Well in the Up direction. In addition to the "station ahead" boards that had previously been installed on each Main line approach to Romford, reminder signs have been provided on some of the platforms at Stratford in the Down direction and at Shenfield in the Up direction. These signs bear the name "Romford" underneath a question mark [8.95]. Reminder signs for Capenhurst station are installed at Bache in the Down direction and Hooton in the Up direction [8.96].

In 2013, reminder signs were provided at some Northern Rail stations between Bolton and Salford Crescent in an effort to reduce instances of trains failing to make their booked station stops. The signs contain the text "your next stop is?" in red letters [8.98], without specifying the name of the next station ahead. Similar signs have subsequently been provided in some other areas.

A gantry carrying colour light signals may span other tracks for which no signal is provided. This can create the risk of a driver taking the wrong signal as applying to his or her train, particularly if the track furthest to the left has no signal. A solution is to provide a 'fake signal' in place of the absent signal. This consists of a black plate with a white diagonal cross [8.99], thus presenting a similar appearance to the cover applied to a colour light signal not in use.
