Cambridge Pilotman working 27 Jun 2012 20:35 #1

Steamer OFFLINE Local Operations Manager Posts: 548 Thank you received: 156	Hi all, When working with pilotmen, under what circumstances may "Dispatch train and wait here" and "Train does not need pilotman" be legitimately used?

Does this include working wrong direction? When working right line the normal signals protect the train, but when working wrong line what prevents second train running into the back of the first?

In ye olden days, at least:

If Absolute Block in still in use (i.e. there's phone communication or similar), the second won't be given permission by the pilotman/signalman to depart until the first has cleared the section.

If AB is not in use (absolutely no communication between the ends), the second train waits the normal amount of time it would take the first train to clear the section, and then proceeds (after several prayers are said by the train crew) at a speed where it is able to stop if it suddenly sees a tail lamp ahead! If the first has to stop out of course, then dets would be placed in rear to warn any subsequent train.

What about for trains going to (e.g.) Whittlesford sidings which need to pass the pilotman but don't use the single line section (because they can reverse on the bit of the down line which is still open)? Can they use that option too?

Yes, subject to the signaller confirming to the pilotman that the 1st train has cleared the section.

Rule Book Module P1 is worth a read. One snippet, detailing the means of protecting the first train in the wrong direction if a second is to follow (which, out in interest, can only be allowed if there is a Handsignalman to control movements back to the proper line):

3.5.1 Signaller controlling wrong-direction movements
You must control trains in the wrong direction by giving instructions to the pilotman and to handsignallers, if appointed. You must make sure these individuals clearly understand what to tell drivers and to work only to your instructions. You must tell the handsignaller if the instructions for the train movement have already been given to the driver.

You can even divide the single line (into two sections on TCB lines) for movements in the wrong direction with an intermediate Handsignalman (or at any number of intermediate signal boxes on an AB line).

Module TS2 (TCB signalling regs) describes the method of signalling during SLW, including the conditions that must be met before the Signalman can allow a train to enter the single line in the wrong direction:

9.3.2 In the wrong direction where there is a handsignaller opposite the signal protecting the crossover
You may allow a train to enter the single line if:
• there is a handsignaller opposite the signal protecting the crossover at the other end of the single line, and
• the line is clear to a point 183 metres (200 yards) beyond that handsignaller.

9.3.3 In the wrong direction where there is no handsignaller opposite the signal protecting the crossover
Note: This method of working (regulation 9.3.3) is not allowed during fog or falling snow.
9.3.3.1
If the crossover at the other end of the single line is facing to the movement, you may allow a train to enter the single line if that crossover is reversed and the line is clear up to and including the overlap of the next signal beyond that crossover.
9.3.3.2
If the crossover at the other end of the single line is trailing to the movement, you may allow a train to enter the single line if the crossover is correctly set and the line is clear to a point 400 metres (440 yards) beyond that crossover.

Obviously there are additional considerations on an AB line (Module TS3), but that's one for another day!
