Date of Photo
"I think you are probably right about the date
of this photo (late-1950s). The tram lines on the Mound were used right
up to November 1956 by the last two services, 23 and 28."
"I think the re-surfacing of Princes Street
was done immediately after that Ė they had started before the trams came
off, and the 28 had been re-routed up the Mound from Princes Street for
its last few months to allow work to progress."
"Not only were the tracks on the Mound lifted,
but the whole road surface was removed. Electric heating elements were
installed below the new surface, as there were apparently concerns that
the buses might not be able to operate in snow.
There was a temperature sensor fixed to a
lighting column on the west side of the street, near the Princes Street
junction. I donít know if it turned on the elements automatically or
Your later picture shows that the heating
elements were quite effective.
Over the years they gradually failed,
sometimes giving a patchwork effect in snow, and I think the whole thing
is now out of use. Maybe someone else has more information!"
