Cobbles were revealed on either side of the line on Upper Parliament Street.

It was uncovered by a group of workmen helping to develop the city's new tram network.

But despite the historic links the old tracks have been concreted over to provide foundations for the latest line.

Same gauge

Stephan Richeux, from Nottingham Express Transit, said the lines were the best tracks they had found during the building works.

"We have dug up little bits here and there but they were the first ones in such a good state.

"It was a reasonably large stretch intact with cobbles around it."

Although it has the same gauge as the new network, which is due to open later this year, the track would useless nowadays as they would sink into the ground under the heavier trams.
