Rule 44 — Unusual Track Signal Conditions

1. (i)A movement that encounters a yellow over red signal within the 30 minutes provided for in Rule 42(a), may proceed on the instructions received from the foreman named in the GBO . If the foreman cannot be contacted, the movement must be prepared to stop at a red signal and, if no red signal is encountered at the location stated in the GBO , the RTC must be advised.
2. (a)In the absence of any of the signals prescribed by Rule 42, between the times stated in a Form Y, a movement must be governed as though the signals are properly placed. Such condition must be communicated to the RTC as quickly as possible.
3. (b)
4. (ii)A movement that encounters a red signal within the 30 minutes provided for in Rule 42(a), must stop, unless authorized to proceed on the instructions received from the foreman named in the GBO . If the foreman cannot be contacted, a crew member must communicate with the RTC as quickly as possible and be governed by instructions received.
5. (c)A movement within the track limits of a Form Y, at the time such protection takes effect, must be stopped unless a crew member is otherwise instructed by the foreman named in the GBO .
6. (iii)A movement that encounters a yellow over red signal or red signal, outside the 30 minutes provided for in Rule 42(a) or without being in possession of a Form Y requiring the placement of such signal, must stop. A crew member must communicate with the RTC as quickly as possible and be governed by instructions received.
7. (iv)If the TGBO / DOB system and the engineering supervisor for the territory indicate that Rule 42 is not or will not be in effect within the limits of the signal, the RTC may authorize the movement to resume normal speed. The engineering supervisor will arrange for removal of the signals that may include having the crew on a movement pick up the signals.
8. (d)In the absence of one or more of the signals prescribed by Rule 43, the movement will be governed by the requirement of the Form V. Such condition must be communicated to the RTC as quickly as possible.
9. (e)A movement that encounters a yellow or green signal without a GBO requiring the placement of such signal, must reduce speed to 10 MPH and immediately communicate with the RTC . The movement will be governed by instructions received from the RTC . If the TGBO / DOB system and the engineering supervisor for the territory indicate that Rule 43 is not or will not be imminently in effect within the limits of the signal, the RTC may authorize the movement to resume normal speed. The engineering supervisor will arrange for removal of the signals that may include having the crew on a movement pick up the signals.
10. (f)When a rail break has been detected by an engineering employee and it is safe to operate over the break at a speed less than posted speed, the RTC will provide GBO protection to affected movements stating the authorized speed over the break and how such location is marked in the field, by either a Rail Break Sign or foreman, at the break. Signals required by Rule 43 will not be in place.
