I had an idea, a few miles ago, that Calder Valley would be better than the main TPE line, due to the relatively self-contained nature of the line - though this obviously won't be the case with Calder Valley services extending through to Manchester Airport/ Liverpool/ Southport.
However, the terrain is a little harder - a shame as there's certainly a good enough frequency from Leeds to Bradford/ Halifax and from Rochdale to Manchester. Feels a bit like the hilly/ remote/ less-frequent bit in the middle of the route is holding the busier bits back a bit.
At least it's a lot more realistic than most of the "Bradford" suggestions on here.
Plans for further GB electrification (outside Scotland) appear to be dead. If the main Standedge trans-Pennine route isn't going to be electrified, what chance for the Calder Valley line? The Westminster govt doesn't care about rail services that aren't to/from London - if they had, the electrified Woodhead line would never have been closed.
Woodhead was predominantly a freight line, for a particular type of freight, coming from Tinsley Yard and the Dearne Valley etc.
When that freight was starting to dry up in the early '80s, there was little use for it as a passenger-only line, given that it doesn't serve anywhere particularly large between Sheffield and Manchester, the passenger service through the Hope Valley is still only half hourly in 2018 (compared to the higher frequency trans-pennine over the Marsden line), plus the fact that it required a separate station at Sheffield (everything else can serve Midland but the Woodhead trains had to serve Victoria, which is some way from the heart of Sheffield, awkward to get to).
I know Westminster are a whipping boy on here but Woodhead's raison d'être was slow heavy freight from industrial South Yorkshire over the Pennines - that freight died off - a second line from Sheffield to Manchester became a luxury (especially given the non-standard electrification/stock).
Bimodes are just a very expensive device favoured by the wallies at DfT to try & justify their opposition to electrification
The opposition to electrification is because the various bits of Government (DfT/ ORR/ Network Rail) are incapable of electrifying lines to a budget and to a timescale.
IF they were capable of doing this, we wouldn't need to cancel electrification of the MML etc due to the massive over-spend on doing half a job on the GWML.
Remember when overhead electrification was so cheap and simple that it'd be better/ easier/ cheaper to replace life-expired Third Rail with wires?
But the current people couldn't deliver the electrification of the first tranche of projects (to a cost/budget), so the rest of the "to do" list was shelved (postponed, cancelled, deferred).
Feel free to blame bi-modes for the situation on the Chase line, the Electric Spine, the Windermere branch, the Valley Lines, Thames Valley branch lines, Wigan to Bolton etc if you'd like, but I don't think those routes were initially planned for bi-modes?
Do you really believe the DfT agenda is that they hate electrification for no rational reason?
I'm not a DfT fanboy but they are just reacting to the changing circumstances.
If Network Rail had done what Network Rail promised to do then there'd be plenty of money for future schemes. Instead, they spent the full budget on doing half-a-job on the GWML and that meant there was no money left for the MML etc.
