Section 21: Stopping Markers

(Page 4 of 6)


Certain stop signals that are positioned a short distance ahead of station platforms are designated as 'remote platform starting signals'. When such signals are displaying a 'danger' aspect, drivers of passenger trains having completed station duties are not allowed to draw up to the signals to await their clearance. They must instead remain at the station, so as to prevent the situation where the train would be partly alongside the platform. So that signals designated as remote platform starting signals are readily identifiable to drivers, experimental signs [21.75 & 21.76] were installed on the Edinburgh - Glasgow line in 2002. The signs, fitted to all car stop markers at the platform concerned, identify the signal ahead as a remote platform starting signal and indicate the means by which the driver should contact the signalman if the signal is at 'danger'. In most cases a telephone number is displayed [21.75], and the driver will contact the signalman using the National Radio Network (NRN) (see Section 19). However, some signs advise the driver to use the telephone on the platform, where one is provided [21.76].

In 2003, a special stop marker was provided on Platform 4 at Balham station [21.77]. The marker applies only to Class 460 Gatwick Express trains. If the platform starting signal (number VC628) is showing a 'danger' aspect, the train must be brought to a stand at this sign, located at a distance of 21 metres from the signal.

A board worded "ATP Car Stop" [21.78] was provided at Aynho Junction in 2003. Its purpose is to indicate to drivers of ATP fitted trains reversing at Aynho Junction and returning to Bicester North, the precise location where to stand. The train must be stopped at a precise location to enable the ATP Train Control system to set up correctly. This board was removed in 2011.

In 2003, further 'remote platform starting signal' identification signs were provided throughout the Scotland Region. The small diamond shape above the telephone number was omitted on these later examples [21.79].

A separate car stop marker may be provided to indicate the stopping position for trains that will turn back at the station [21.80 - 21.83]. These indicate a different stopping point to the normal position, for trains that are to reverse.

Special stop markers for reversing trains, with a purple background [21.84], were installed at Ipswich station in 2003 and subsequently also at Witham.

At stations managed by Southeastern, a car stop marker with an additional "T" sign underneath indicates the stopping position for services that will turn back [21.85].

A special stop marker was provided in 2004 on the approach to signal NS301 situated to the north of Birmingham New Street station [21.86]. The sign applies to drivers of Class 390 'Pendolino' trains to ensure that the pantographs of those trains do not come to rest too close to the nearby booster transformer.

'Selective Door Operation' (SDO) is a system for limiting the amount of power operated passenger doors that can be opened on a train when stopped at a station with a short platform. In connection with this, boards were provided in 2004 at stations where Midland Mainline Class 222 'Meridian' units call [21.87]. The figure on the board informs drivers of Class 222 units as to the number of cars that may have their doors opened at the platform concerned, so that the Selective Door Operation can be carried out accordingly. SDO boards at stations managed by Southern have a blue background [21.88]. Class 465 'Networker' units also have a facility for Selective Door Operation. Depending on the circumstances at a particular platform, a sign may be installed bearing the initials "SDO" with a letter "F", "R" or "B" for 'front', 'rear' or 'both', as appropriate [21.89].

Markers in connection with SDO are provided at certain stations between Salisbury and Exeter. Placed facing the track, they bear the words "Selective Door Opening Marker" together with a triangle pointing to the left or right as appropriate, inside which is stated the applicable direction, "Up" or "Down" [21.90].

In 2004, car stop markers with a letter "X" [21.91] were installed at each end of the short platform at Bearley station. These apply only to Chiltern Railways services formed of 3-car Class 165 and 168 units.

At stations where trains are required to stop adjacent to platform monitors provided in connection with Driver Only Operation (DOO), the associated stop markers may bear the words "car monitors" [21.92] rather than the usual words "car stop".
