New Glasgow subway trains will run with no staff on board from 2025

The trains will be part of a £289 million upgrade to increase frequency, and will have open-plan, walk-through interiors replacing separate carriages and allow passengers to see along tunnels from windows at each end.

Full speed testing of the first of the 17-strong fleet is underway in the circular system overnight.

They will initially be controlled by drivers when they start carrying passengers in 2023.

However, operator Strathclyde Partnership for Transport (SPT) has announced full “Unattended Train Operation” (UTO) is due to begin two years later, with no drivers or staff on board.
