I live very near loughton station and can see trains going past out my window, i'm the sidings side of the station. But anyway, why is there full passenger trains with all lights on and everything going past at around 2:30 til 4:30 am when the first train on the central line isn't until ~4:50 from loughton sidings to epping. This has been happening now for about 3 nights and i just want to know what they're doing and they're not in service as i looked at the tfl website's platform display board thing that said there was nothing. Are there many trains in the middle of the night coz if there were i'd be out drinkin a lot more and all over london  thanks |

Probably keeping de-icing fluid applied to the conductor rails to ensure that the passenger service can run when it's due to start up. Otherwise the risk is that ice would form in the hours when no trains run, preventing the first trains of the day from drawing power.

Yes, I would also guess they would be sleet trains. They run on the Met for the same reasons.

There known as sleet trains, and operated by the night crews from Hainault and Leytonstone. Basically they run on all open sections of the line spraying de-icing fluid on the conductor rails, after the close of traffic (engineering hours) that's why they would not appear on the TfL website.

You might see them on some Apps that you can get that show the next trains. My phone showed the empty trains the other night differently to the TfL site.

do they run through Stratford station (and then reverse at Liverpool Street)? If not how are the conductor rails there kept clear of ice?

I can't speak for the Central, however on the Northern Line the 95 stock sleet trains have been running Hampstead to Edgware in order to cover the section from the tunnel portal to Golders Green platform, supplemented by battery-loco trains running the same section but also doing some of the sidings like Colindale. On the Barnet side they've been doing Highgate Depot to High Barnet / Mill Hill, and they've also been doing Morden Depot to Morden Station. Other sections would be manually de-iced, for example by Technical Officers. |

How does this affect the staff doing engineering/maintenance stuff on the tracks? I'd assumed (possibly incorrectly) that most bits of track were walked on and checked most nights.

Engineering Hours would be cancelled. What has been happening on some lines is that Engineering Hours would finish early at around 0320 to allow running of sleet trains as there are some inspections that must be carried out at certain intervals, plus all the stuff that has broken during the day has to be investigated or fixed! It would be interesting to find out the cost of all the lost work |

Presumably it would still be safe for staff (on overground sections) to walk along the line, just not do a lot of repairs?

For some work yes, using the same protection arrangements as in Traffic Hours. Obviously anything too instrusive (such as use of scaffolding) cannot be done. From a signalling point of view a large amount of work can only be done when there are no trains (such as work on the locking) |

It would be interesting to find out the cost of all the lost work It would be factored in under contingencies. Seems a pretty meaningless statistic - but I forget - the bean counters are in charge. |
