The 2018 replacements for the current Moorgate trains can only be be six carriages long since that's the max platform length at Moorgate through to Highbury & Islington, below-ground platform lengthening is impossibly expensive.
A link to Govia's plans here. The new trains in 2018 will be fixed 6-carriage units - no more short trains. The internal layout with wide corridor connections (like the Overground trains from Highbury & Islington) will allow more comfortable standing in peak hours. Train frequencies will also be increased.
I'm voting for Matthew Cuthbert, as Govia's New Governor for Good Ideas, to introduce 12-carriage trains at rush hours, with instant effect. At intermediate stations such as Harringay or Hornsey the driver will align his front six carriages with the platform for a two-minute halt while doors to rear six carriages remain locked and armed guards keep the excess and baying Ladder mob at bay. After two minutes driver proceeds to align his rear with the platform to allow the Harringay/Hornsey hordes remnant to board. At terminal stations - Moorgate, Welwyn GC etc - the new 2018 improved carriages should allow the rear carriage "customers" to proceed patiently forward from carriage to carriage till they reach the platform. Who needs costly longer platforms for longer trains?
On second thoughts, these may just be cost-effective solutions to non-existent problems and IfAQs. Please advise. OAE has been avoiding rush-hour commute(r)s for the past dozen years.
How would you deal with the six rear carriages overlapping the junction to the platforms at Moorgate, thus blocking access to the opposite platform?
Seriously, since the Moorgate suburban lines towards Hertford and Welwyn are fairly self-contained, improved signalling could surely allow a much more frequent service. If Trains can be dispatched from Walthamstow on the Victoria Line every two minutes, it should surely be feasible at Moorgate, too.
This is not a self contained line though. It's part of the East Coast main line and the Hertford Loop, north of FPK/AAP. There is the need to factor in trains on the main line to KGX too, and while there may be separate lines here and there, running 2 trains per minute to MOG seems somewhat overly ambitious!
I think the 'slow' lines between Moorgate and Hertford/WGC are pretty much self-contained, using platforms that main line trains do not visit. The main line trains take the 'fast' lines, and the outer suburban trains usually stop for the first time at Potters Bar (using the 'fast' lines). The might be the occasional need for a freight train or two on the slow lines, but I am sure they could be signalled for a much more frequent service than the current one if required. The northbound Hertford Loop uses a flyover to cross the main lines, so there is no conflict there.
The Northern City branch itself was once a working relic, but is no longer if you look at the huge numbers of passengers who interchange there with the other lines at Highbury and Islington. But yes, a link with the W&C Line or even a new tunnel through Cannon Street (to eliminate the need for that main line terminus, as was done with Holborn Viaduct and [a bit late in the day] Broad Street) would be very useful.
But if you just run it as an end to end service, with every train stopping at every station, it is straightforward as long as you have the signalling infrastructure in place. At present the Finsbury Park to Moorgate section has a train about every five minutes during the rush hour, which probably means that each of the two platforms is occupied by a train for about seven minutes at a time (allowing two minutes to access the platform from the platforms junction on arrival and one minute on departure - giving ten minutes in total for each of two trains). That's probably about as much as can be achieved with the current signalling and driving system (though possibly up to three minutes could be shaved off the turnround by having another driver at Moorgate to ready to leap into the rear cab and take the train northwards again. That's presumably how they sometimes manage to turn a Victoria Line train round in one minute at Walthamstow Central). But with a modern signalling system it shouldn't be impossible to double the present frequency, giving a five-minute service to/from both Hertford North and WGC. Whether that can be justified economically is another matter, since the current service, due to be enhanced anyway in a couple of years, is more or less adequate outside peak hours.
