There needs to be a transport system linking major points around the city centre. DLR (Docklands Light Railway) is the template with a mix of overground, ground level and underground to avoid traffic. It is relatively cheap to build and run compared with rail, tram and underground systems. https://en.wikipedia.org/wiki/Docklands_Light_Railway DLR carriages hold just under 300 passegers wth each train comprising of 2-3 carriages. City fans at the Etihad will be going both ways. I am no expert but a Phase 1 route starting at Piccadilly then Etihad, Northern Quarter, Victoria Station, Salford, Docks, Old Trafford, Trafford Centre seems lke a good start for sustainability. Other stops could be included. Phase 2 would be a southern line linking the Trafford Centre with Piccadilly so it becomes a circle line. This would solve many of the problems of getting around, linking transport systems and moving large numbers at events. DLR has enabled the huge growth in East London. A similar system would do the same for Manchester. Now is the time with so much development taking place. GMC should take the lead and engage partners to put plans in place. The project is at least as important as the Manchester Ship Canal in its day and is essential if Manchester is to cement itself as a major global city and attract further investment.
