A double track crossing is being installed on Central Promenade for the horse tramline.

But the arrangement differs from the original design shown on the drawings on the MyProm page and in the application that received planning consent.

These show the tracks converging as an 'interlaced' arrangement as they cross the road between Esplanade Lane and Castle Mona Avenue.

Quite what the advantage was over a simple single track crossing the road was not clear.

But the crossing as now being constructed has the two lines separated.

The Department of Infrastructure said the design has been ’simplified’ following a review.

Critics of the Prom scheme suggest that the horse tramway isn’t simply being reinstated but its over-engineered replacement is paving the way for a future modern tram system.

A spokesman said: ’The design has always shown double tracks crossing the carriageway before joining together as a single line heading south past Broadway.

’The double tracks were shown on the planning drawings in an interlaced arrangement which provided minimal track separation.

’We have reviewed this detail with the rail regulator and simplified the arrangement to separate the double tracks.’

The Department of Infrastructure’s planning statement for its 2018 application (18/00003/B) notes: ’From Castle Mona Avenue, the track will cross the southbound carriageway as a twin track, combining on the sea side kerb as a single track, from where it will run to the Peveril Square roundabout, stopping at a siding.

’At the War Memorial, a passing loop/run around will be provided.’
