The recent correspondence about the M74 and Glasgow subway extension (Letters, December 12 and 13) for transport to the 2014 Commonwealth Games contrasts with London's approach to the 2012 Olympics.

The London Olympic Delivery Authority aims to encourage 100% of spectators to travel to the Olympics by public transport, walking and cycling.

Transport links will be transformed around Stratford, with extensions to the London Docklands Light Railway, a rebuilt East London line, and 140mph trains on High Speed Line 1.

In marked contrast, in Glasgow the M74 extension is described by James Kelly MSP as a "crucial part of the Commonwealth Games infrastructure". In fact, this urban motorway, a product of 1960s transport thinking, would choke the local roads around the Games venues with more traffic and parked cars, giving an international demonstration of how not to plan for major events.

Glasgow has the biggest rail network outside London. Most of the Games venues are near railway lines. Strathclyde Partnership for Transport has an excellent opportunity to re-establish Glasgow as the "dear green place" by providing new stations to serve the sporting locations. As discussed by your correspondents, the best way to serve Parkhead is by extending the Argyle Line and introducing a new fleet of high-performance urban Metro trains on a Dalmuir-Parkhead east/west route.

This would also serve the Scotstoun and SECC locations and connect at Glasgow Central with trains to Mount Florida for Hampden. The planned National Hockey Centre could also be served from the Argyle Line by reopening the station at Glasgow Green. The Ibrox and Kelvinhall venues are near subway stations.

In a city with a low level of car ownership and a poor health record, building more urban motorways is not the future.

The aim of politicians should be to ensure that the Common-wealth Games leave a lasting legacy of urban regeneration and sustainable transport.
