Overground speed - or lack thereof
The speed of the Overground from highbury down to shadwell is underwhelming
to say the least. Slow ponderous acceleration up to probably nothing more than 25mph and then braking from what seems like 300m before the station. Are the 378s just not up to the job of running a metro service or is there a deliberate policy of a leisurely pace to operations? -- Spud |

The East London Line was always a rather leisurely affair in its Underground days so I suspect the Overground has inherited the same line speeds. -- DAS |

I haven't been that far down on it so I'll take your word for it, but the pace on the ELL is a joke. Coupled with waiting for the train to leave highbury plus frequent pointless waits at Dalson Junction it makes it a poor 2nd choice for getting to east london from there when the Victoria+Jubilee to canada water is - on my tests - is frequently 10 minutes faster to do probably almost twice the distance. -- Spud |

Once we were allowed to depart (after umpteen freights and stock transfers were routed across our path) the driver gave us a spritely run which probably clawed back about 2 minutes of the delay. This meant it was less of a mad dash at Gospel Oak for the Barking train. If that "catch up" time wasn't in the run times then the connection may well have been missed extending my journey time by 15 minutes. Of course you could look at it from another point of view - if your train had been going faster it could have got past the crossover before all those other trains turned up. Several of the routes do have closely spaced stations so there's little point drawing a load of electricity to accelerate quickly and then have to jam the brakes on. It's also not terribly comfortable for passegers. Doesn't seem to bother anyone on the ATO controlled tube lines which accelerate the trains like scalded cats. Punctuality and reliability are highly valued by passengers even if Its supposed to be a turn up and go metro service. I doubt anyone seriously checks the timetable beforehand. So long as trains turn up every 3 or 4 minutes thats all that matters. The final point to make is that the slowish running speed doesn't seem to deter passengers given how overloaded the trains are. If they were Well its detered me. If I continue on the victoria and change at green park to the jubilee it almost always gets me to canada water quicker than the ELL even though its a much longer distance. see the point. Let's face it the network is vastly better than what was there before and it is receiving hundreds of millions of extra investment to raise capacity. Personally I think the ELL should have remained a tube line and stayed on its own tracks. Running over NR lines is just asking for delays plus the longer the route is the more than can go wrong. -- Spud |

Very much so, of the 4 southern routes only the single stop branch to New Cross doesn't have to fit in with other services. Good timekeeping is also important when each branch only has a 4tph service - it's only between Highbury & Islington and Surrey Quays that it's truly a "turn up and go" service. |

I rarely use it myself but the trains are standing only at Norwood Junction in the mornings, and rammed by the time they get to the old ELL. On that route it's also had the side-effect of a far better service to London Bridge on the Croydon route, which surprised me - the reduced London Bridge service has less crowding. The downside is stations between New Cross Gate and Anerley have a far worse service to East Croydon and beyond than previously; as a result Norwood Junction is actually used as an interchange these days. Despite all the NR line running it's remarkably reliable! |

Was that really the only way to fit the trains in? https://www.tfl.gov.uk/cdn/static/cm...-timetable.pdf As far as I understand it from what was said when it was introduced, yes. It required massive service changes on the London Bridge - Croydons - beyond route to accommodate the Overground timetable, and presumably a clockface timetable on the individual branches was a goal. Stations beyond West Croydon lost their stopping services to London Bridge and their semi-fast services other than a handful in the peaks. Many services via West Croydon were diverted to the fast lines between Norwood and London Bridge (resulting in the pretty odd situation that Norwood Junction has a better service to London Bridge between the peaks than in peak - 6tph fast and 2tph stopping) Likewise stations south of London Bridge now have a poor direct service to East Croydon. Two of the 6tph (Horsham via Gatwick) have since been changed to make a stop a New Cross Gate as a slight improvement to that (with another benefit that the original ELL stations are now a single change from Gatwick) The losers were definitely passengers from south of the Croydons wanting the intermediate stops, and passengers from those intermediate stops travelling south of Croydon. |

(And Sydenham - New Cross Gate is 12tph - at a very even pattern too - which must be close to the realistic maximum for the line I'd have thought? If I remember right from when I lived there that's double the service there was before London Overground) |

Maybe they could stick an extra couple of carriages on the back... the trains are walk-though, after all. Incidentally, I was on an S stock recently going through Mansion House, I think, and messages appeared on the LED display warning that the rear door would not open. However, I could see that the same message was appearing on the displays all the way through the train. It seems lazy to me that they tell people in the front carriage that the rear door won't open. |

The design element I'd change there is that the visual indication at the door of "door out of use" does not display until the release is pressed, whereas it'd be more useful if it appeared on departure from the previous station.

I suppose the top speed is so they can be cascaded in the future to elsewhere around the country because its certainly overkill on their current routes. I still think S stock running on the ELL as a tube route terminating at new cross + gate would have been a better choice despite extra traffic from further south since interchange would have been fairly easy. -- Spud |

I suppose the top speed is so they can be cascaded in the future to elsewhere around the country because its certainly overkill on their current routes. It isn't - the linespeed on the slow lines south of New Cross Gate is largely 60mph (if probably not reached that often in normal service. ECS though...) I still think S stock running on the ELL as a tube route terminating at new cross + gate would have been a better choice despite extra traffic from further south since interchange would have been fairly easy. Where would the extra services from further south terminate? No terminating facility at New Cross Gate, and no capacity at London Bridge. Same applies for terminating from the north at New Cross Gate. Terminating 12 tph there would be challenging, perhaps not impossible but the knock-on effect of a problem would be far bigger than with multiple quieter terminuses. People have always been able to change at New Cross Gate for the ELL (well, apart from the long stretches of it being closed). They tended not to and interchange numbers were tiny, probably due to the inconvenience, and the infrequency of the ELL and its limited route. A train load of people changing at New Cross Gate would cause chaos there, even after they've finished rebuilding it. |

Where would the extra services from further south terminate? No terminating facility at New Cross Gate, and no capacity at London Bridge. They could have had reversers further up the line. Lets be honest - the real raison d'etre for the ELL now is to get people from highbury to shadwell or canada water to get to canary wharf so bypassing a huge chunk of central london. The south bit is mainly irrelevant since trains already went to london bridge where people could already get the jubilee anyway. Same applies for terminating from the north at New Cross Gate. Terminating 12 tph there would be challenging, perhaps not impossible but the knock-on effect of a problem would be far bigger than with multiple quieter terminuses. How do other tube lines cope then? Where there's a will... route. A train load of people changing at New Cross Gate would cause chaos there, even after they've finished rebuilding it. That logic didn't seem to stop the closure of the farringdon to moorgate branch so its odd TfL seem to think it applies in south london but not north london. South london is already oversubscribed with national rail services, it didn't need another. The ELL with a high frequency fast tube service would have been a better option for those of us north of the river than the dog slow service we ended up with. -- Spud |
