presumably you based your calculations on the 52 seater M5000s not the 58 seater ones?
Different numbers of seats? I've never noticed anything different between individual units when I've been on the trams, except for the difference between mrk3s and mrk1s/2s (which seem the same, I saw 1007 today though which was different as I've been told on here before, but didn't get a ride on it). How many seats do the old trams have?
As a Sheffield resident we can only envy the new routes that are now in place around Manchester.
There's a few things that don't cause me to be envious of Metrolink. Take today, I arrived at the stop to find a tram pulling in, by the time the machine had spat out my ticket the tram was gone. 12 minutes wait on a windy platform is not much fun (ok, I think the line I was using was supposed to have a 6 minute frequency but I think I waited more than that before giving up and going back to the flat to wait for 20mins after deciding I'd miss the hourly frequency train I was aiming for if I waited any longer for the next tram). Would be handy if they had waiting rooms, or ticket-purchase facilities were available on board so you can just jump on the tram (although, as I've said on this topic before, the Piccadilly fridge needs sorting regardless).
The only down side with the new trams are the seats, after 20 minutes it was num bum time
For me the main downside (followed closely by lack of ticket-issuing) is the lack of seats. Not nearlly enough alot of the time in my experience.
A route was chosen about ten years ago for an extension from East Didsbury to Stockport town centre, but it does not seem likely to happen in the near future or perhaps ever. It would involve some expensive bridgeworks. Also I gather Stockport council have never been keen on it, I'm not sure why, others may know better.
Another gripe I have is having to go all the way into MAN to link up with National Rail. The cost seems high compared to going to Stockport via ALT, but the heavy-rail frequency at ALT is only one an hour. I apprieciate that paths into Piccadilly would be a problem, but could frequency from Knutsford/Northwich to Stockport be improved with the extras teminating at Stockport (or reversing towards Crewe)? Mind you, lack of rolling stock would probably put a stop to that anyway. As it is capacity on my trip today was inadequate, the service provided by single pacers (think I saw a single 150/2 going in the other direction though). Would be nice if you could buy through tickets from Metrolink to heavy rail stations (rather than only the other way round, although I don't think you can do that with a railcard anyway).
Why? There were wires there before, what was wrong with whatever held them up?
your going to have a 650vDC system on the tram meet a 25kvAC system on the trains ?
How much would have to be different to make a tram able to run on heavy-rail infrastructure (I'm not sure how close a tram-train is to either extreme, and whether there are multiple ways to strike that balance)? The Navigation Road single track seems to be one hell of a bottleneck and I've thought that if the trams were dual-voltage and could run on heavy-rail infrastructure they could have just electrified that section as a 25kv AC double-track line shared by National Rail and Metrolink services.
