The old Mumps station was inconveniently sited the wrong side of a major road, accessed via an unpleasant subway. The new tram stops are far more convenient and the new alignment is well designed, with much segregation and effective prioritisation at junctions.
I know. They didn't go to the effort of moving a line from a tunnel to a street running section for nothing. I was trying to illustrate my point about how LR conversion may or may not be irreversible.
A pair of those 50m articulated tram-train units coupled together would be similar in size and capacity to a deep level London tube train or one of the 3 car DLR trains.
Indeed. Again the point was that if absolutely required, the segregated sections of the Valley Lines could, in future, be hived off again and turned into a heavier metro with even more capacity. Sub-surface line signalling and S7/8 stock would be an increase in capacity over 100m doubled trams.
Where has it been confirmed anywhere the Valleys are getting tram-trains, or that tram-trains are being considered?
How can you tell from looking at a non-specific planning application?
If freight is to be permitted on the Valley Lines after conversion, there is no choice. Even if there were a choice, the case for tram-trains is incredibly strong. For a small increase in per-vehicle cost you get complete compatibility with the HR network, massively reducing the costs of delivering the same passenger-facing benefits.
A good LR conversion scheme should gain DfT support, because any way to reduce the subsidy needed for the HR network in Wales is a good one. The UK government is ultimately going to be paying for HR services in and around Cardiff regardless of how it devolves power, so some amount of investment upfront for long-term efficiency savings is entirely worthwhile.
