Remains at 34tph from mid-May but end-to-end running. 90 mins per peak of 36tph in November 2016 - maybe. I suspect they want to try out stepping back at both ends of the line with 34 tph to iron out any issues. Is this the first instance of a line emptoying stepping back in more than one location at the same time? |

With the new timetable in May the stepping back period is being extended and is going to be happening at weekends as well, also T/Op's will be picking up/getting off after/for meal reliefs for the first time. |

There will still be the odd Seven Sisters reversing train/staff train, but far less than there is now. |

I suspect they will want to keep a few Seven Sisters terminators for staff access to the depot.

it was planned to run through to Walthamstow via the terminating platform at Seven Sisters on a frequent basis.
Has this been abandoned?

Will the new timetable be end-to-end all the time, or will there still be Seven Sisters reversers during the off-peak? Off-peak all trains will run through Brixton-Walthamstow. 27tph it was planned to run through to Walthamstow via the terminating platform at Seven Sisters on a frequent basis. Has this been abandoned? All Walthamstow trains will use pfm.3 There will still be the odd Seven Sisters reversing train/staff train, but far less than there is now. The staff runs, to/from depot and Seven Sisters pfm.4 will only operate every 30mins M-F, hourly at weekends. The new timetable is now shown in increments of 5 seconds, rather than ¼ ½ ¾ of a minute, as previously used: eg. the first NB departure from Brixton is at: 05 26 55. |

Can someone define "stepping back" for me?! Driver B drives the train into Walthamstow Central, gets out, presses the "rear cab clear" plunger and begins walking along the platform to the front of the train. Meanwhile, driver A, already on the platform, gets on the front of the train, checks that the rear cab clear visual is showing and that his colleague is not still on the train, gets ready and goes when the signal clears. Driver B arrives at the front of the platform. Driver C drives the next train into Walthamstow Central, gets out, presses the "rear cab clear" plunger and begins walking along the platform to the front of the train. Meanwhile, driver B gets on the front of the train, checks that the rear cab clear visual is showing and that his colleague is not still on the train, gets ready and goes when the signal clears. Driver C arrives at the front of the platform. Driver D drives the next train into Walthamstow Central, gets out, presses the "rear cab clear" plunger and begins walking along the platform to the front of the train. Repeat. |

Can someone define "stepping back" for me?! Services on some Lines (Victoria, Piccadilly, Jubilee) are so frequent that it is not possible for the driver to bring a train to a stand at a terminal station and walk to the other end of the train in the time available, the train would be due to depart well before this. Stepping-back was introduced, so that the first driver relaxes, slightly!, before he makes his leisurely way to the other end of the platform, and picks up maybe the train behind, two trains behind, or even three trains behind the one he bought in. |

I don't know if it's still done, but I remember seeing this carried out on the Bakerloo at the E&C |

Brilliant, thanks.
Was there not a practice at one time called double-ending, where the incoming driver stayed at the front, became the guard, and the incoming guard drove the train from what was now the front? It was referred to in the Moorgate accident report anent the Northern City. May have been entirely unofficial.

I understand double ending was unofficial, but perfectly safe if the guard had qualified as a driver. The driver would, of course, have been a guard in the past. Most commonly done on shuttles, to avoid a lot of walking, (especially if it was raining), and helped to keep the guard's hand in while he waited for a driving vacancy to come up. It was, of course, entirely up to the driver whether he felt the guard was competent.
Stepping back has long been the practice on the Drain, especially in the mornings. It is not so much the length of the train that was the limiting factor, but having to swim against the tide of humanity going the other way to get to the other cab. Even going with the flow, you will see the train setting off back to Waterloo when you have only walked half the length of the train.

Even going with the flow, you will see the train setting off back to Waterloo when you have only walked half the length of the train. Used to be quite common at East Finchley. If a driver doesn't show up for any reason one option is to detrain and reverse over 23 crossover, then shunt it round to platform 2 for its next trip. Normally the DMT would jump in the back cab to save time. Remember one Sunday it had to be done 3 times during an afternoon. Much less common nowadays, as many desk duty managers no longer have train licences. |

The obvious question is why? Is it to increase the pressure on station staff/train operators to keep the service on time? |
