Sir – Having trams instead of buses seems an attractive idea; but some practical difficulties are being overlooked. I wonder if High Street is wide enough to take two pairs of rails while allowing space for goods vehicles unloading.

Trams cannot overtake each other and it is possible that, for most of the time, there will be two almost unbroken lines of trams, causing tailbacks extending beyond the centre of the town.

Large vehicles and the emergency services will have to join the queues of trams. Cyclists will have to overtake on the left where they will meet with passengers boarding and leaving the trams. The lines also present hazards for cyclists as they can get trapped in them unless crossed at an oblique angle.

One wonders, too, how the trams will be managed on The Plain where they will be converging from three arterial routes, involving six pairs of tracks, to cross Magdalen Bridge, and then be guided back to their respective rails for the return journeys.
