The current timetable has services across the whole route being interdependent on each other, with services to Larkhall, Cumbernauld, Dalmuir, Whifflet and Milngavie interworking with each other. As such, a delay on one part of the network spreads across the rest of the route, and it takes much longer to restore services following disruption. Dwell times at on some services through the city centre do not allow enough time for passengers, while on other services they are longer than necessary.
The poor performance here has also resulted in a decline in passenger numbers as passenger sought more reliable modes of transport.
3.0 December 2020 Timetable
The December 2020 timetable introduces changes to improve performance, making the service more reliable and attractive for passengers. Various changes have been made, including changes to dwell times at city centre and key interchange stations to give time for boarding and disembarking.
The new timetable is designed to minimise the knock on impact of delays on different parts of the network. A train that works a service from Dalmuir to Larkhall will return to Dalmuir; a train that works a service from Dalmuir to Whifflet will return to Dalmuir. Therefore, a delay at Larkhall is less likely to impact passengers at Whifflet.
