Glasgow's Ibrox station, one of 15 in the city's Clockwork Orange network, has had a £1.7 million makeover, bringing in improvements such as "smart" gates and ticket machines and an improved CCTV system.
The station is the first in the south of the city to be refurbished under Strathclyde Partnership for Transport's (SPT) £288 million modernisation programme for the subway system.
The new-look facility was formally launched by Deputy First Minister Nicola Sturgeon, the MSP for Glasgow Southside.
She said: "I am delighted to see these improvements at Ibrox and look forward to the modernisation programme being rolled out across the rest of the subway system.
"Six of the 15 subway stations are in my Southside constituency and I am a huge fan.
"It's a great way to get about Glasgow and I know many of my constituents would be lost without it."
The work at Ibrox was carried out between April and November last year, and means it now joins Hillhead and Partick as a fully upgraded station.
SPT said key developments at the facility include a new ticket office and retail space, new signage for passengers, hearing loops, brighter energy-efficient lighting and installation of the new smart ticketing technology.
SPT chair Jim Coleman said: "Ibrox station not only looks great, it also shows we are well on track to deliver a fully-revamped and technologically-advanced network.
"Through introducing smart technology we are at the forefront of developments in fully-flexible ticketing solutions in Scotland - almost 20,000 smart customers are already benefiting from more convenience, faster journeys and increased security.
"Hopefully other operators will see this and we can work together to make this even better by rolling it out across other modes of transport, creating seamless travel from subway to bus, to rail and ferry services in future."
The next revamp, an upgrade of Kelvinhall station, is expected to be finished in time for the Commonwealth Games, being hosted by Glasgow.
Glasgow's iconic subway, the only one in Scotland, was the third underground railway to exist in the world when it opened in December 1896.
It runs on a loop almost 6.5 miles-long, which extends both north and south of the River Clyde and links such places as Kelvinbridge, Kinning Park and Buchanan Street.
