How busy is the Goblin line? I would have thought that TfL would want to add to capacity on this line too? Is a 3rd car planned in the future.

I would think a third car would be added in the near future.

That moquette is just, ergh.

The 150s aint that bad, but these 172s [Aesthetically speaking] look the business. Cant wait to have a spin on them.

Dont think the GOBLIN passenger group or others would like it, but I would give up a Kidney to see the 104/121/115s back.

Based on a crude measurement on google maps air photos, there is approximately 70ft (21 metres) between the end of the westbound platform and the bridge abutment. Equally approximately there is 182ft (55.5 metres) between the eastern end of the westbound platform and the toe of the points.

If all this space can be used (not likely), then that gives you up to 76.5 metres of extra platform without crossing the High Road or fouling the junction. Wikipedia gives a car length of 23.62 metres, so at least in theory there should be plenty of space for a platform of sufficient length to accommodate three car Class 172s.

Chris, I do believe that the 172s do come in 2 cars or multiples of 2 cars. That is where I suspect the problem lies.

London Midland have ordered 3-car class 172s.

I'd pay top dollar to see the old Mechanicals back on this line... it was better when they had the blind up! But still, yeah, can't wait for the 172's.. I'm sure the lines' user group is also awaiting their introduction with much impaitence... www.barking-gospeloak.org.uk

It should be going up to 4tph from May or the end of the blockade. As to the speeds, they have resignalled the line, but done nothing to the infrastructure. There are parts that are terribly slow and should be upgraded for faster running

Services are already 3tph in the peaks, which is probably the most which can be managed with the available units and the end-to-end timings.



4 tph doesn't fit in so well with the Bakerloo line service between Queens Park and Stonebridge Park / Harrow & Wealdstone. Currently there are 6 tph Bakerloo to/from Harrow and another 3 tph to/from Stonebridge Park. 3tph are easy to timetable around this pattern (basically fitting into the other Stonebridge Park 'slots'). 4 tph would mean having to flex the Bakerloo line departures from Harrow (currently trains are xx.02 and every ten mins, DC trains are xx.17 and every 20 minutes, splitting the ten min gap into two five min gaps).

Another consideration is that the class 172s are 23m coaches, so will need an extra 6m of platform for a 3 car units than the equivalent 20m unit.

Quite true, 6m extra for 2 car trains and 9m for 3 car trains

(Although if the cabs don't have to be on the platform, the numbers could be a bit less).
