HELENSBURGH commuters have been warned to expect major disruption to their train journeys home on Wednesday evening.

ScotRail cancelled all trains between Glasgow Queen Street low level and Helensburgh Central, as well as on several other routes, at around 3pm because of a signal failure.

The company announced: "Unfortunately we've got a fault with our signalling system in the Yoker area meaning we're unable to run trains between Bowling and Drumchapel and also between Dalmuir and Scotstounhill.

"Our staff are on site and investigating and we'll provide you a further update when we have more information."

As this article was published at 3.40pm, ScotRail was forecasting that disruption would continue until 8pm.

Services were completely suspended on the following routes:

- Glasgow to Balloch

- Glasgow to Helensburgh

- Glasgow to Milngavie

- Glasgow to Motherwell via Rutherglen

Valid train tickets were accepted on First Glasgow's Glasgow-Balloch/Helensburgh route, though that service – along with many others through Glasgow city centre – was also disrupted on Wednesday due to road closures caused by the Glasgow 2018 cycling time trial event.
