Reading these forums, I see many fantasy ideas about push-pull 442s saving the nation and it got me thinking; my line (the Furness line) is about to lose its 185s due to the TP North capacity upgrade. So I was thinking; how would I fix it?
I'd work in combination with the Windermere line as well. Splitting and joining of services on this route at Lancaster makes the concept a lot more viable.
In terms of infrastructure, the Furness line suffers from some slow speed limits which could be raised with little work. I think an aim of 60mph between Barrow and Ulverston (where there is a lot of curves as it goes around the Furness peninsula), and 90/100mph between Ulverston and Carnforth would be a reasonable aim. It would also be a good idea to sort out the junction with the WCML at this time, removing the slow flat junction raising the capacity of the WCML at the same time. Electrification would be on the cards as it would allow good use of old EMUs - although Grayling wouldn't be too happy.
Initially (while the work to modernise the infrastructure continues), it would be an aim to give the line 1tph clock face. The line can deal with 3tph in both directions from what I've seen in the current timetable, but a consistent service will help significantly. As electrification comes online, high quality modern EMUs (ideally refurbished 350/2s from WMtrains as they already have the 110mph capability for the WCML) would operate a new service pattern. All times are from Barrow-in-Furness.
xx16: Slow to Preston, calling at all stations
xx46: Semi fast to Manchester Airport, calling at Ulverston, Grange-over-Sands, Arnside, Carnforth, Lancaster (where it joins with another service from Windermere), Preston, Wigan North Western, Manchester Oxford Road, Manchester Piccadilly and Manchester Airport.
By having all services on the line at least to Preston, the bay platforms at Lancaster can effectively be decommissioned (with Platform 5 available for Morecambe services). Routing what would be 8 car trains through the busy Wigan-Manchester corridor allows the service to easily cope with demand between what currently is the busiest section on TPEs Manchester-Scotland services. SDO would be installed using the Tracklink system (as used on SWR) allowing shorter dwell times and a more efficient service.
The Cumbrian Coast may become isolated somewhat in terms of no through running on the Furness Line, but a possible extension of Newcastle services may solve this issue. It would be an aim to harmonise Cumbrian Coast services in the new timetable with an easy connection on to the slow service at xx16.
I think I rattled on a bit, but overall it would be my way of sorting out what has the potential to be a relatively busy line. I'm looking forward to seeing some of the ideas that come along, though!
