Monday should see the final stage of the long running signalling upgrade on the Jubilee Line come to completion, as the line starts running close to its theoretical peak rate.

Last August, the network upgraded from running 24 trains per hour to 27 trains per hour – and from Monday, it will go to 30 trains per hour in the main Willesden Green to North Greenwich section.

It will peak at 32 trains per hour during the Olympics – and possibly thereafter.

To put that into context, they have gone from a train every 2.5 minutes a year ago during the peak to one every 2 minutes, which is about as close as they can get if you want to allow time for people to get on and off the trains at stations.

That’s about 6,500 extra people per hour in the morning and evening peaks – or an extra few centimetres of space in the crowded trains.

According to District Dave, the full running rate will be:

M-F peak: 28-30tph Willesden Grn-North Greenwich, 24tph NG-Stratford
M-F off-peak: 15thp Stanmore-Stratford, 3tph Wembley Park-Stratford, 3tph Willesden Grn-Stratford

SAT before 12:00 and after 20:00: 20tph
SAT 12:00-20:00: 24tph

SUN 12:00-20:00: 20tph

Possibly worth noting that they have to lay on nearly as many trains on a Saturday afternoon as was available during the working week rush hour a year ago. Such has been the rise in demand for the line even during off-peak hours.

Looking at the TfL journey planner – the change is visible when I look at the trains leaving during evening rush hour, for example, from Canary Wharf to Willesden Green.

Last Monday Next Monday
17:27 17:27
17:30 17:29
17:32 17:31
17:34 17:33
17:36 17:35
17:39 17:37
17:41 17:39
17:41

That’s one extra train squeezed in between 5:27 and 5:41.

Although shaving a minute or two off the journey time is almost unnoticeable, I have actually noticed a change in the trains running since the upgrade last August. The trains appear to pulse a bit as they run along, with accelerating and decelerating as the automatic train control maintains the gap between each train.

I have also noticed that my ears pop when the trains go into the tunnels at Canning Town, and occasionally through the tunnels – which they never did before the speed increase.

Actually, slightly irritating, but in a liking the fact that the network has been upgraded sort of way.

An empty Jubilee Line carriageI doubt the trains will be quite this empty in the rush hour – alas.

    I am glad to hear about improvements on the Jubilee Line. However, feels like this line is absolutely hopeless now matter the number of upgrades. Every time I look at the status panels, 80% of the time I see Jubilee with part closures or severe delays.

    Glad I don’t use it much.

      Um Ana isn’t all these upgrades the reason for the delays?
      When they are done there shouldn’t be so many!

    I hope you’re right, Kevin
