FIXED SIGNALS. | |||||||||||||||||||||||||||||||||||||||||||
Fixed signals. |
34. Fixed signals consist of distant, home, starting, advanced starting, calling-on, warning, siding and shunting signals. In certain instances signals are repeated, in which cases the additional signals are known as repeating signals. |
||||||||||||||||||||||||||||||||||||||||||
35. (a) Semaphore signals are generally of the two-position type, the indications being shown thus :-- Distant Signals.
Stop Signals (Home, Starting and Advanced Starting).
|
|||||||||||||||||||||||||||||||||||||||||||
(b) Other types of signals include :--
|
|||||||||||||||||||||||||||||||||||||||||||
(c) Automatic semaphore stop signals worked without control from a signal box are in some cases distinguished by the arms being pointed at the ends. |
|||||||||||||||||||||||||||||||||||||||||||
(d) Back lights, where provided for fixed signals, show a white light to the Signalman when the signals are at Danger, and are obscured when the signals are in the Clear position. |
|||||||||||||||||||||||||||||||||||||||||||
(e) Fixed signals, as a rule, are so placed as to indicate by their positions the lines to which they apply. Where more than one home, starting or siding signal is fixed on the same side of a post the top arm applies to the line on the extrer left, and the second arm to the line next in order from the left, and so on. At some places only one arm is provided and a letter or number exhibited to indicate the line over which the train will run. |
|||||||||||||||||||||||||||||||||||||||||||
Normal position of fixed signals. |
(f) Except where otherwise authorized, the normal position of fixed signals is Danger, or Caution in the case of distant signals. |
||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||
DISTANT SIGNALS. |
|||||||||||||||||||||||||||||||||||||||||||
Distant signals. |
36. (a) Distant signals are placed at some distance in rear of the home signals to which they apply, and where necessary below the home, starting or advanced starting signal, applicable to the same line, of the signal box in rear. |
||||||||||||||||||||||||||||||||||||||||||
(b) Where only one distant signal is provided for a diverging junction such signal applies to all trains approaching it. |
|||||||||||||||||||||||||||||||||||||||||||
Observance of distant signal. |
(c) The Caution position of a distant signal indicates to a Driver that he must be prepared to stop at the home signal to which it applies. |
||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||
STOP SIGNALS (Home, Starting and Advanced Starting). |
|||||||||||||||||||||||||||||||||||||||||||
Home signal not to be passed at Danger. |
37. (a) Where starting signals are provided the home signal must not be passed at Danger except as follow :--
Where a home signal controls the entrance or trains into the section ahead the provisions of Rule 38 apply to such signal. |
||||||||||||||||||||||||||||||||||||||||||
Train stopped at home signal where no starting signal. |
(b) Where a starting signal is not provided and it is necessary for a train which has been stopped at the home isgnal to be brought within that signal before the line ahead is clear, the Signalman before lowering the home signal must verbally inform the Driver as to the state of the line ahead and what is required of him. If, when the train is stopped at the home signal, it is not possible for the verbal communciation to be made Rule 40 must be observed. When the line ahead is clear, the signal for the train to proceed must be given by the Signalman showing the Driver a green hand signal held steadily. |
||||||||||||||||||||||||||||||||||||||||||
Starting signal not to be passed at Danger. |
38. (a) Where advanced starting signals are provided, the starting signal must not be passed at Danger except as follow :--
|
||||||||||||||||||||||||||||||||||||||||||
Signal controlling entrance to section ahead not to be passed at Danger. |
(b) Home signals where starting signals are not provided, starting signals where advanced starting signals are not provided, and advanced starting signals, control the entrance of trains into the section ahead, and must not be passed at Danger except as follow :--
|
||||||||||||||||||||||||||||||||||||||||||
Operation of signals. |
39. (a) When a stop signal is at Danger the stop signal next in rear of it worked from the same signal box must not be lowered for an approaching train until the train is close to such signal and has been brought quite, or nearly, to a stand. During fog or falling snow, the Driver of a train stopped, or nearly stopped, at a signal next in rear of a starting signal must, when practicable, be verbally informed that he is only to draw forward towards the starting signal.
|
||||||||||||||||||||||||||||||||||||||||||
Use of advanced starting signal during fog or falling snow. |
(b) During for or falling snow--unless track circuit or other apparatus is provided in connection with the advanced starting signal to avoid the necessity for trainmen having to go to the signal box to carry out Rule 55--a train must not be drawn past the starting signal towards the advanced starting signal except for station duties or shunting purposes, or where special instructions are issued to the contrary. |
||||||||||||||||||||||||||||||||||||||||||
Driver to draw slowly forward when signal is lowered but not to pass out of sight of Signalman. |
(c) The Driver of any train which has been stopped or brought nearly to a stand in accordance with clause (a), must, after the signal has been lowered, draw slowly forward to the next signal and be prepared to stop at the signal box if necessary. When proceeding towards a starting or advanced starting signal at Danger, he must (except for station duties or shunting purposes, or as shown below) only proceed as far as is necessary to leave the last vehicle well clear of junction points and junction crossings, and, as far as practicable, within sight of the Signalman. Where there are no junction points or junction crossings the Driver must bring his train to a stand in a convenient position for the carrying out of Rule 55. Where track circuit or other apparatus is provided in connection with the starting oradvanced starting signal, to avoid the necessity for trainmen having to go to the signal box to carry out Rule 55, the Driver must draw forward to the starting or advanced starting signal. |
||||||||||||||||||||||||||||||||||||||||||
Signalmen communicating verbally with Drivers. |
40. When a Signalman wishes to communicate verbally with a Driver he must stop the train at the signal next in rear of the signal box for this purpose, but if it is not then possible for the verbal communication to be made, he must lower the signal (or calling-on signal where provided) for the train to draw forward, and stop it at the signal box by exhibiting a red hand signal. The Driver must not proceed until he clearly understands the verbal communication and has received the necessary authority. |
||||||||||||||||||||||||||||||||||||||||||
Trains allowed to proceed under Block Reg. 5. (Warning arrangement.) |
When a train is allowed to go forward under Block Regulation 5, and a stop signal is provided in advance of the box, the Signalman must, if the train has not already passed the Home Signal, bring it quite or nearly to a stand at that signal before lowering it, and must as the train is approaching the box, exhibit to the Driver, a green hand signal, held steadily, which the Driver should acknowledge by giving a short whistle as an indication that he understands that the section is clear to the next Home Signal, but that the station or junction ahead is blocked. The necessary fixed signals may then be lowered for the train to proceed. If the Driver does not acknowledge the hand signal, the signal controlling the entrance to the section ahead must not be lowered until the train has been brought to a stand at it. If there is not a stop signal in advance of the box, the Signalman must stop the train in accordance with Rule 40, and verbally instruct the Driver that the Section is clear to the next home signal but that the section or junction ahead is blocked, after wich a green hand signal, held steadily, must be exhibited to the Driver. If the train is assisted by an engine in rear, or two trains are coupled together, a green hand signal, held steadily, must be exhibited to the Driver of each engine. Where a warning signal is provided the green hand signal must not be exhibited. |
||||||||||||||||||||||||||||||||||||||||||
When train brought to a stand at signal controlling entrance to station ahead. |
(b) Except where instructions are issued to the contrary, when a train has passed the signal box and is brought to a stand owing to the signal controlling the entrance to the section ahead being at Danger, the lowering of such signal must be taken by the Driver as an indication that the section is clear to the next home signal but that the station or junction ahead is blocked, and he must regulate the speed of his train accordingly. |
||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||
REPEATING SIGNALS. |
|||||||||||||||||||||||||||||||||||||||||||
Repeating signals. |
42. Repeating signals, where provided, are placed in the rear of, and repeat the indication given by, the signals to which they apply. When a repeating signal indicates that the stop signal is at Danger, the Driver must proceed cautiously towards the stop signal. |
||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||
MULTIPLE-ASPECT SIGNALS. |
|||||||||||||||||||||||||||||||||||||||||||
Three-aspect signals. |
43. Where three-aspect signals are provided, the Caution aspect indicates to a Driver that he must be prepared to stop at the next isgnal, and the Clear aspect indicates that hes muxst be prepared to find the next signal showing either the Caution or Clear aspect. |
||||||||||||||||||||||||||||||||||||||||||
Signals having more than three aspects. |
Where colour light signals having more than three aspects are provided, one yellow light indicates to a Driver that he must be prepared to stop at the next signal, and two yellow lights indicate the he must be prepared to find the next isngal showing one yellow light. |
||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||
CALLING_ON SIGNALS. |
|||||||||||||||||||||||||||||||||||||||||||
Calling-on signals. |
44. (a) Calling-on signals, where provided, are placed below home signals, or starting signals where advanced starting signals are provided, and when the calling-on signal is lowered the Driver must draw forward cautiously as far as the line is clear. The lowering of the calling-on signal does not authorize the next stop signal to be passed at Danger. |
||||||||||||||||||||||||||||||||||||||||||
(b) Except where authorized, the calling-on signal must not be lowered until the train has been brought to a stand at it. |
|||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||
WARNING SIGNALS. |
|||||||||||||||||||||||||||||||||||||||||||
Warning signals. |
45. (a) Warning signals, where provided in connection with Block Regulation 5, are placed below the signal controlling the entrance to the section ahead. The lowering of the warning signal must be taken by the Driver as an indication that the section is clear to the next home signal, but that the station or junction ahead is blocked and he must regulate the speed of his train accordingly. |
||||||||||||||||||||||||||||||||||||||||||
(b) The warning signal must not be lwoered until the train has been brought quite, or nearly, to a stand at it. |
|||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||
SHUNT-AHEAD SIGNALS. |
|||||||||||||||||||||||||||||||||||||||||||
Shunt-ahead signals. |
46. Shunt-ahead signals, where provided, are placed below the signal controlling the entrance to the section ahead, and when lowered, authorise the latter signal to be passed at Danger for shunting purposes only, and a train must not proceed on its journey until the signal controlling the entrance to the section has been lowered. |
||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||
GROUND SIGNALS (DISC OR DWARF), SEMAPHORE SIGNALS WITH SMALL ARMS, AND SMALL COLOUR LIGHT SIGNALS, USED IN PLACE OR DISC OR DWARF SIGNALS. |
|||||||||||||||||||||||||||||||||||||||||||
Ground signals. |
47. Disc or dwarf signals, semaphore signals with small arms, and small colour light signals, are used to regulate the passage of trains from a siding to a running line, from a running line to a siding, between one running line and another, and to control shunting operations In cases where these signals have a yuellow disc or arm or exhibit a yellow light they may be passed, without being lowered, for movements in a direction for which the signal when lowered does not apply. |
||||||||||||||||||||||||||||||||||||||||||
Signal controlling exit from siding. |
48. (a) Where a signal is provided to control the exit from a siding and a train is ready to depart, a Driver must not proceed until such signal has been lowered, nor must a Driver whilst waiting for the signal to be lowered, allow his engine to stand foul of any other line. |
||||||||||||||||||||||||||||||||||||||||||
(b) When a signal applies to more than one siding and more than one engine is in the sidings, a Driver must not move towards the signal so as to foul any other siding until he has been instructed to do so by the person in charge of the shunting operations. |
|||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||
TRAINS SHUNTING OR RUNNING IN WRONG DIRECTION. |
|||||||||||||||||||||||||||||||||||||||||||
Application of fixed signals. |
49. Distant, home, starting, advanced starting, calling-on, warning and shunt-ahead signals apply only to trains travelling in the proper direction on the running lines, and must not be used for any other purpose, except as provided in Rule 197. Trains moving in the wrong direction on any running line or shunting from one running line to another, or shunting into, or out of, sidings connected with running lines, must, unless fixed signals are provided for such movements, be signalled verbally, or by hand signal, as occasion may require. |
