Rule 611 — Automatic Interlocking Signal Indicating Stop

1. (i)a crew member, after opening the box marked “switches”, will observe panel lights, where provided. If those of the conflicting route(s) are lighted and no conflicting movement is evident, the crew member will open the knife switch and may then allow the movement to proceed;
2. (a)When no other movement or track work is evident;
3. (b)Where a pushbutton is provided, to enable a reverse move to be made over the crossing, the crew member will open the box, depress the pushbutton and be governed by signal indication. If the signal fails to clear, the instructions contained in paragraph (a) must be complied with.
4. (ii)(MULTI-TRACK) in the box marked “switches” where lights are provided to indicate the approach of a movement, if those of the conflicting route and those of the same railway on the adjacent track are lighted and no other movement is seen approaching, the crew member will open the knife switch and may then allow the movement to proceed;
5. (c)A movement required to switch within or into automatic interlocking limits must, after complying with (a)(iii) leave the knife switch open until switching is completed. When the knife switch is in the open position, signals governing the switching may be considered suspended but only while switching.
6. (iii)where lights are not provided, or where those of the conflicting route(s) are not lighted, the crew member, after opening the knife switch, must wait five minutes, unless a greater period is specified in special instructions and posted in the box marked “switches”, before permitting the movement to proceed; (MULTI-TRACK) - When the lights of the same railway on the adjacent track are not lighted and no other movement is seen approaching, the crew member will contact the RTC before opening the knife switch, to ascertain whether or not a movement is closely approaching on that adjacent track to prevent displaying STOP indications to such movement.
7. (d)When track work is evident; i.e. when encountering a “840.3 Protection” visible indicator or a special lock on the box marked “switches”; after stopping at the signal, the movement must not proceed beyond the signal until instructions have been received from the foreman. When so authorized by the foreman to proceed, the movement must move at RESTRICTED speed to the next signal or Block End sign.
8. (iv)after complying with (i), (ii) or (iii) the movement must then operate at RESTRICTED speed to the next signal or Block End sign; and
9. (v)after the movement has occupied the crossing, the switch must be closed and the box marked “switches” locked.
