I lot of interesting posts over Christmas, and a level of detail that I applaud!
TfGM and tramsThe only project currently under construction is the second Manchester crossing (incidentally partially funded with the EU regional development fund) and the associated revamp of Victoria Station. There are plans for a line to Trafford Centre and beyond. Anything else has not got to the planning stage. This includes tram-train to Marple/Rose Hill. Stockport MBC is one of the few boroughs of GM not to have trams. Anyone know who else?
Technically speaking it is possible to run trams on rail lines and vice versa. Karlsruhe were the first to do this in modern times, and places in Germany and the Netherlands followed suit. In the UK there are issues with different voltage, loading gauge and signalling but they are not insurmountable. Indeed in Essen, if memory serves, there was a bus that turned into a railcar!
And vehicles can use a dual voltage system (I think there was a loco in Belgium that handled3 different systems and a loco in Southern Region that could use 3rd rail DC or overhead AC) and Sheffield are the first UK city to develop this.
The question is do we want it? The advantage is the flexibility of using heavy rail systems that can access street-running networks. In answer to one of hatter76 questions, yes, we could take a feed off the line near Ashburys and run it into the Ashton tramline that uses Piccadilly Undercroft. Trams are quicker and 4-car units are easily joinable. They are also cheaper to run than heavy rail units.
Here come some of the downsides. If we had trams, then why not driver-only operation? That will require a lot of negotiation with train crews and TOCs like Arriva. And train modification. And infrastructure would need changing. And has been pointed out, it's difficult to run 2 systems of overhead electrification. (I have a dream of riding an electric train from Manchester via Marple to Sheffield one day. Northern Powerhouse is a great concept that Osbourne fronted. But even that ran into difficulties at the design planning stages.)
All these things cost. Would we get a much better service? E.g. you wouldn't be able to take your bike or your dog on a tram under present regulations. We don't have a rapid urban transport "metro" style system, but we do have something close with tram + electrified urban routes. Like Marple. I haven't seen a business case that is definitive either way.
NorthernOn the heavy rail side, Arriva have arrived. And with their franchise, there is a contract to make trains more frequent and longer. This should include Marple. The 142 Pacers will be phased out of the whole UK by 2020 (or it’ll have to be modified but I don't see that coming).
We are building a chord from Victoria to Piccadilly, adding platforms 15 and 16 to Piccadilly and then much later getting HS2/3. Unlike in the 60s, we get trains and their use now.
Friends of Marple / Friends of Rose HillIf you are interested in railways and in making the train trip and stations locally more pleasant, may I tactfully suggest that you come to one of our meetings? In the past we've had Annette Finney (now Cllr) and then John (of this blog) too. And of course, more people of other political opinions! We've recently had passenger counts, got children singing at Christmas at Marple, and Father C came to Rose Hill. By train of course.
