More trains in 2012

Between Mile End and Stratford! (Also non-stopping through Blackfriars and Cannon Street)
;D

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.

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.

As far as I know, individual line usage stats haven't been updated on TFL's website since 2009. Though their Annual Report for 2010/11 shows an increasing trend in the overall number of tube passengers.

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.

Honest answer: don't know.

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.

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.

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?

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!

The next phase of the Jub upgrade occurs this Sunday 25th doesn't it?

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

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.

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?
