However, if the line has been examined for a reported track defect you must tell the driver of each train that is to pass over the affected
line:
* a track defect has been reported
* to proceed at caution over the affected portion of line not exceeding 20 mph (30 km/h).
You must continue to do this until a competent engineer has confirmed that the affected portion of line is safe for normal operation.

TS1 20.6 When a track circuit fails to clear or
shows occupied for some other reason. Before the passage of the first train:
You must make sure that no train has been signalled over the affected portion of line and that the last train over the affected portion of line has passed clear of the track circuit concerned and one of the following applies.
* That train has occupied and cleared the overlap of the signal or block marker beyond the affected portion of line.
* You have received train out of section for that train.
* You have been told that the train has passed out of the section with tail lamp attached.
On a single line or bi-directional line, you must also carry out the instructions shown in module P2 Working single and bi-directional lines by pilot.
Unless you are sure that the line is not obstructed, you must arrange for the line to be examined as well as carrying out the following instructions.
75
TS1 20.6.2 When a track circuit fails to clear or shows occupied for some other reason. If the first train to pass on a line immediately next to the affected line
before the affected line is examined, the driver of this train must be told:
* what is happening
* the locations between which the adjacent line is affected by the track circuit
* to pass the affected portion of line at caution
* to report as soon as possible if anything is wrong.
76
TS1 20.6.3 When a track circuit fails to clear or shows occupied for some other reason. First train to pass over the affected line:
You must stop the first train to pass over the affected portion of line and ask the driver if the line appears to be **clear as far as can be seen.**
If the driver confirms that the line appears to be clear as far as can be seen, you must:
* tell the driver what has happened
* reach a clear understanding with the driver as to which portion of the line is to be examined
* tell the driver to pass the signal at danger and to proceed at caution over the affected portion of line
* tell the driver not to exceed 10 mph (15 km/h) through any tunnel on the affected portion of line
* tell the driver to report the state of the affected line at an agreed point ahead of the affected portion of line.
77
TS1 20.6.5 When a track circuit fails to clear or shows occupied for some other reason. If the affected track circuit again shows clear:
If the affected track circuit shows clear before the signalling technician arrives, but a train has not yet passed over the affected track circuit, you must carry out the instructions for a first train passing over the affected line.
After you have given the driver the
necessary instructions, you may clear the signal or issue an MA. If it is then proved that the line is clear, you may resume normal working.
If a train has already passed over the affected track circuit, you may resume normal working.
78
79
TS1 20.6.6 When a track circuit fails to clear or shows occupied for some other reason. If, after a train has passed over the affected track circuit, it shows
occupied and clear at intervals, and as a result there is a possibility that a signal or signals could revert to danger in front of a train or affect an MA which has been issued, you must treat the track circuit
as having failed.
If you have been treating a track circuit as failed but the affected track circuit shows clear before the technician arrives, you may resume normal working as long as:
* at least three trains have passed over the affected track circuit
* the track circuit has been observed to have operated normally for and between each train.
80
TS1 21If you become aware that a long time has passed after a train has entered a section, you must try to contact the driver to find out the cause.
If you cannot contact the driver, until you have found out what is wrong, you must:
* stop each train on any adjacent line travelling towards the overdue train
* tell the driver of each train the circumstances regarding the overdue train
* instruct the driver to proceed at caution when the signal is cleared or an MA is received
* tell the driver to report what has happened with the overdue train
* signal each train normally.
If another line is not available, you must get help from a competent person.
If the entrance to the section is controlled by another signaller, you must tell that signaller.
81
TS3 DEFINE Absolute block section
The line between the last stop signal (which can be a section signal or an intermediate block home signal) controlled from one signal box, and the home signal controlled by the next signal box.
82
TS3 DEFINE Block signals
A stop signal that controls the entrance to, or exit from, a block or intermediate block section.
Home signal: the first stop signal controlled by a signal box that controls the exit from an absolute block section.
Section signal: a stop signal that controls the entrance to an absolute block section or an intermediate block section.
Intermediate block home signal: a stop signal that controls the exit from an intermediate block section, and the entrance to an absolute
block section.
83
TS3 DEFINE Clearing point
The point beyond the home signal up to which the line must be clear before a train can be accepted as shown in regulation 3.4.
84
TS3 DEFINE Intermediate block section
The line between the section signal and the intermediate block home signal worked by the same signal box in the same direction of travel.
85
86
TS3 DEFINE Station Limits (Taken from NOI)
The line between the home signal controlled by a signal box and section signal controlled by the same signal box in the same direction of travel.
87
TS3 Principle of AB?
The principle of the absolute block system is to prevent more than one train being in a section on the same line at the same time.
88
88
TS3 3.2 When can you send train out of section:
You must observe the train as it passes the signal box and make sure it has a tail lamp at the rear.
When the train has passed beyond the clearing point, or passed beyond a facing junction and you have set the points for another line which is clear to the clearing point of that line or has been shunted clear of the running line
