The
Union
Canal flows through Polwarth on its way from Edinburgh to
Glasgow.
Although within the boundary of Merchiston Community Council,
Harrison Park – on the north bank of the canal – is commonly taken
to be part of Polwarth. Behind the tenements at the north of the park
runs a footpath which was formerly track
bed for the main line of the Caledonian Railwayen route to
the now-closed Princes Street railway station in the centre of the city.There was once a
Merchiston
Station on this line near the park.
