THE Subway’s brand new trains have now arrived in Glasgow - and they will give passengers a unique new perspective.

Inside passengers will now be able to walk the entire length of the train and enjoy an open front view into the tunnels.

But passengers will have to be patient about seeing them first hand as the trains must undergo rigorous testing before being marked safe to use.

The arrival of the rolling stock was hailed as a "fantastic day" for the Subway as part of its multi-million pound renovation scheme.

In a major milestone for SPT, the arrival of the new trains will start the beginning of an intensive testing programme by manufacturer Stadler to ensure the trains are fully fit for purpose.

It is only after this extensive testing by Stadler that it will be handed over to SPT to enter passenger service.

SPT Chairman, Councillor Martin Bartos, said: "This is a fantastic day for the Subway and for everyone involved in the delivery of the Subway modernisation programme.

"We are delighted to see the first new train in Glasgow.

"It’s a big day for the project team who have worked tirelessly to achieve this milestone for the organisation."

The first of the new trains will now begin a lengthy, offline testing period while work continues to install the new communications and controls systems in all stations and tunnels.

The new system is necessary for the trains to run in passenger service.

The new trains and communication and control systems are all part of the £288million Subway modernisation programme, which also includes a major refurbishment of the system’s 15 stations.

Work underway is a complete overhaul of the Victorian tunnel system.

It sees the replacement of the Subway’s main infrastructure, including tracks and the ramps and turnouts section where the trains enter and exit the system.

Due to the unique dimensions of the Subway, the new train sets are the same length and size as the existing rolling stock.

Two more new trains are due to be delivered by the end of the summer for the first phase of testing.

Work on the £288million Subway Modernisation programme began in July 2011 with the refurbishment of Hillhead station.

To date, 11 stations out of 15 have now been refurbished, with another two - St George’s Cross and Cowcaddens - due to be finished by Summer 2019.

Work on the last two stations - Kinning Park and West Street - will begin before the end of 2019.
