Even more interesting is that it was the two rail options for which people voted.
As I said i think both are equally worthy which is why I didn't vote, we could of course afford both if the government didn't spend so much money on useless overseas adventures.
One option you didn't give was trams on heavy rail. This would work for Portishead and Severn Beach. Trams use heavy rail complete with freight trains and come off into the centre of Bristol at a convinient point to commence street running. This not a complete takeover of the heavy rail lne as in Manchester Wolverhampton Nottinghm and Croydon. Heavy rail trains still run run on the same lines as the trams.
It works in Kassel. As well as dual voltage trams Kassel have ED trams that traverse an unelectrified branch to Wolfhagen. So at Willhemlhohe Hbf you have everything type of train from ICE downwards plus freight and trams using the lines through the station.
Conversley in Zwickau Heavy Rails DMUS of the Vogtland Bahn tranverse the street tramway (tram metre gauge so three rails) to a station in the centre.
It can be done. But "they" seem to think it's unsafe.
Fair point, and I believe that Tom Harris is on record as saying that the Government is studying tram-trains.
