22. Whenever the line at Newton Junction is obstructed, or an Engine or Waggon is being shunted, the attention of the Pointmen on the Liverpool and Manchester Line must be called to the circumstance by =ringing the Bells= at the top of the Incline. =Two Bells= are fixed for the Pointmen at the Junction, whereby Signals may be exchanged between them and the Grand Junction Pointman. 23. Whenever a Train is ascending the Warrington Incline, whether for Liverpool or Manchester, at the same time that a Train from either of those Stations for Warrington is approaching Newton Junction, the Pointman will stop the =latter= until the former Train has passed the curve; he will also take care that an interval of not less than =five minutes= is allowed between the passing of any two Trains towards Warrington. 24. If, when any Liverpool and Manchester Second Class Train has arrived at the Warrington Junction, a Birmingham Train is seen coming up the Warrington Inclined Plane, the Engineman must stop, and allow the Birmingham Train to =pass before him= to Liverpool. 25. If the Birmingham Coach Train overtake a Liverpool and Manchester Second Class Train more than 3 miles distance from Liverpool, the Second Class Train =must shunt=, if there be an opportunity, to allow the Birmingham to pass. N.B.--The same rule applies equally to Third Class Trains. SECTION III. DIRECTIONS FOR THE USE OF DETONATING SIGNALS IN FOGGY WEATHER. 1. These Signals are to be placed on the Rail (label upwards), by bending the lead clip round the upper flange of the Rail, to prevent its falling off. When the Engine passes over the Signal, it explodes with a loud report, and the Driver is instantly to stop. 2. The use of Fog Signals is to be in addition to the regular Day and Night Signals of the Line, which must be first exhibited. 3. Whenever an accident occurs to a Train, by which the Line is obstructed, the Guard is to go back 600 yards, to stop any Engine or Train following on the same Line, and as he proceeds he is to place on the Rail, at the distance of every 200 yards, one of these Signals; and on his arriving at the end of the above-mentioned distance, he is to place Two Signals upon the Line of Rail. 4. Should the accident occasion the stoppage of both Lines of Rail, the Guard is to send the under Guard or Fireman in advance of the Train, to place the Signals on the opposite Line of Rail to that which the Train is on, in the same order as to distance as is above directed for the Guard, by which precaution both Lines of Rail will be protected.
