According to the TLF stike blurb, the central is operating an Epping - Liv St shuttle. I remember when I was on the central line we could reverse E to W at Lst via to two sidings, but as i recall, there is no facility to reverse back east. (unless there is now a method to reverse of the westbound back east now!!)  |

What about the trailing crossover west of the platforms? OK, you can't do it with people on board, but with the reduced service ATM it shouldn't be a problem.

How difficult is it to run reduced timetables and unusual crossovers with the ATO on the Central Line, compared to conventionally signalled lines?

Based on a conversation I had over several pints with a gentleman who was involved in installing the system: quite straightforward.
Local site computers will update off the basic TT, by site.
(I think; we were quite trollied by the end of the evening! ;D)

Plus you can reverse west to east via both the sidings. The only reversing move that can be done at Liverpool Street in ATO is east to west from the platform over the crossover and can be done with passengers.

The only reversing move that can be done at Liverpool Street in ATO is east to west from the platform over the crossover and can be done with passengers. It's been many year since I've seen that move - only happens during service disruptions, and even then most moves would be done via the sidings, as reversing in the platform holds the service up. There is no rusty rail move in the current WTT. When trains reverse weat to east via the sidings (double shunt), the rear end cab is in the tunnel, so the driver changing ends has to "butterfly" the door open, then "butterfly" the door closed, then quickly jump in the door before it shuts! |

Door cock. Allows local operation of the doors.

Am I missing something, why would the Train Op have to leave the train to change ends especially in a tunnel siding? |

Train arrives in westbound platform - detrains - driver has to go to rear of train to take it into the siding, the rear cab is in the tunnel. |

But why, is the platform too short to have both the west and east cab at the station?

On Thursday trains were detrained on the WB, driven in coded to the Limit of Shunt and brought back EB across 10 points, the operator having changed ends in the tunnel.
Later on the trains were 'double ended' by spare crews and the operator met his own train back on the EB

I think the answers have conflated two things:
1. Relieving T/Op boarding the train.
2. T/Op walking down the berthed train, tipping out and then getting into the rear cab.

I misread that post, I thought the train was already in the sidings...sorry for the confusion. |

It's probably the practicality of walking through two doors rather than eighteen. And I'm not even sure that the middle pair wouldn't be out the side and in again anyway. |

The other possibility is that the T/OP can close the doors on the last door by means of the porter button, then sneak in the end passenger door. As for walking through the train, the T/OP needs to assist with detraining, so this is not practical.
