The first of Glasgow's brand new Subway trains has been seen on the city's system for the first time.
Strathclyde Partnership for Transport (SPT▸ ) said two trial exercises had taken place successfully in the Glasgow Subway.
The first bespoke train - built by contractors Stadler and Hitachi - rolled into the system on 5 December.
Tests were carried out while the Subway was closed to the public at night.
The milestone is part of the system's modernisation programme and marks the start of extensive testing of the new trains that will continue throughout next year.

Glasgow subway trains do of course have a bit of a track record where cuteness is concerned, since they have to be small and round to make best use of the tunnels. They also need small wheels, for a train, at about half a metre. Being made by Stadler means some other design peculiarities too; the two centre vehicles have one one bogie apiece. More details from
their data sheet.
