2013 will likely be next, I don't feel like the entire Olympic media circus and the hotel prices :') Is it possible to get my Oyster Card's history via an FoIA request to see what lines I might have used? xd
EDIT: Also, at least it's the Jubilee, so heat shouldn't be an issue.

I am going from Westminister to Stratford on Sunday is there any sections which are always fast no matter if you are early or late? Between Mile End and Stratford! (Also non-stopping through Blackfriars and Cannon Street) ;D |

When I'm in London, and usually around peak. The only trains I really had to cram myself in are the 92ts, which are nearly always busy. I live on the Jubilee and it's the same for me. It's often busy, yes, but there is space for me to board, so not as bad as everyone makes out. However I do live on the northern end of the Jubilee, I think the Canary Wharf - London Bridge section is often packed to the brim. |

I don't often travel on the Jubilee in the peaks, but east of Waterloo trains are frequently crowded. Eastbound there are quite disproportionate loadings with the front of the train more crowded that the back - it's a long walk from the back of the train to anywhere useful at Stratford, and only slightly better at West Ham.

And I thought LT had learned from passenger flows (see D78 and 83ts doors) and overcrowding. Guess not.

And I thought LT had learned from passenger flows (see D78 and 83ts doors) and overcrowding. Guess not. Eh? The layout of the train or its doors isn't the issue here. The key cause of the overcrowding is simply too many people trying to travel at the same time. No amount of doors of any size (beyond a certain point) will solve this to any significant degree, although train layout can impact on dwell times and thus service reliability - compare the Class 313 and 378 trains on the North London Line. Jubilee line trains are already pretty close to optimal given the constraints of the tunnel size, crashworthiness, and requirements for seats. The disproportionate loadings on trains (which is not exclusive to the Jubilee Line at all) is due to station design and human nature. People will always crowd around the closest point on the train to the platform entrance at the station they get on at and at the point on the train closest to the platform exit at the station they are travelling to. I don't know of any way of minimising the impact of this other than having multiple entrances and exits at stations, and distributing the location of them along the length of trains at various stations (i.e. don't have all the entrances at the same point), neither of which are always possible for various reasons. At both Stratford and West Ham the Jubilee line was added to existing stations in a position that was constrained by various factors. A bigger rebuild of Stratford would have been possible to move the platforms closer to the concourse, but only at massively increased cost and probably worse pedestrian flows too. A bridge from the JLE platforms to the DLR ones would have been good, but may have lead to overcrowding of the latter platforms that had to be built on the site of the old North London Line platforms that were essentially unchanged in dimensions since at least the 1980s. |

Speaking of overcrowding I wonder when some new usage stats for the Jubilee lines will be released.

Sorry if this i not relevant but during strikes does the Jubilee line drive Manually? Today its only open between Stanmore and Finchely road i think it would be pritty pointless to run ATO?

Not pointless at all, it means the timetable can be kept to and passengers got to their destinations as quickly as possible. In fact it is probably more important to use ATO so that the smaller number of available trains can do as many journeys as possible.

If drivers wanted to use PM mode could they or would they have to notify the line controller?

I was talking to one of the Drivers today at Stanmore and I asked Him are these trains running on Full power yet. I know I have asked many times before but he said that since ATO trains have been upped in power but he does not think that they are on their true preformance mode yet. I think the 1996 stock is in a poor state at the moment and the motors don't sound very healthy on some trains. Speeds between stations is quicker but on longer sections the speed is cut right down almost always the time! Will 30 trains per hour solve this? Happy new year to you all  |

All Jubilee line trains have enhanced traction software. As I have already explained the more lightly laden the train is, the more chance you will have of experiencing the maximum acceleration rate.

The train from Stanmore to Baker street the one I was on was lightly laden.
Unless the train I was on was unlucky and did not have much power?
however I find the ride quality under ATO poor allot of jerking and on off nature of power as many people have said the Central lines ATO is much smoother can the Seltrack system be modifed for passanger comfort?

Pass then. You should be able to feel the train accelerate faster than before. Out of interest were you sitting in a Motor or Trailer car?
The on / off traction characteristic is very much a feature of SelTrac, as I don't think it has a coast mode. You get a similar effect on the DLR. Basically it is the ATO system trying to match the speed profile required.

Dan

Coasting could reduce energy consumption easily if it was put to good use, Central Line would benefit greatly.
Regularity is more important to me than a quicker train. Though quicker trains can help to maintain regularity.

I rode the Jubilee line from Waterloo to Green park today twice.
Line speed was a crawl and I doubt we were close to the train infront.
Train was quick out of the station went faster then heavy braking then sudden burst of power coast then brake and yet it is 27 trains per hour surely they should be faster?

I had this on the 27th going from Stratford to WAT, once we got in tunnel it was start up, coast..start up, coast..all the way to Waterloo, and the doors were slow to open at every station, opening before the PEDS.

The train was strange as it was going very slow between stations then coming into stations it speeds up then slows down. The way ATO drives the train needs to be sorted out I know it might be the nature of Seltrack but other ATO systems are much smoother and quicker.
The motors must be worn out with the constant power on off cycle!
At the moment I am sure trains were much quicker Manually driven!

There are plenty of driving strategy variables, many to do with energy efficiency. Most modern ATO systems will allow a train to creep slowly up to approx. 50m behind a train in front at a station. As the train in front departs and clears the platform, the train behind accelerates sharply into the station, and then decelerates when required by the breaking curve. This helps decrease platform reoccupation time. |

Where's the Stanmore trains in the M-F Peak? Do they make up the 24tph NG-Stratford?

Does anyone on here know what on earth has been happening on the jubilee line recently?? There has been a spate of signal failiures recently (bit like the old system really!)
Yesterday morning there was a failiure at North Greenwich and now there's yet another.
"Suspended between Green Park and Canary Wharf and severe delays on the rest of the line due to signal failures."
That line is cursed.

This evening was a trial of the third peak for the Olympic events, looks like its gone belly up.
Still plenty of Jubilee Line top brass were due to be about to see the Olympic timetable in action.

Yesterday was some power kit feeding the signalling failed at North Greenwich. Tonight was two points failures (not signalling) - one at Waterloo and then one at London Bridge as trains started to reverse there.
Very frustrating for both staff and customers.

Apparently 1996 stock is not on its maxium 100% power yet I know somebody who works on the Jubilee line and he says it is not quite on 100% yet. They have had some perfromance upgrade yes! And I know under TBTC that they are faster yes!
Is there anyway of knowing if they are defiantly on 100% power?

This test occured on Friday 23rd March 2012 and is intended to be a simulation of the third peak train service for the Group A lines – Jubilee, Central, District and Circle & Hammersmith – which will take place during the Games.
