Commuters could be hit hard on Tuesday morning as some rail services between Glasgow and Edinburgh were cancelled by ScotRail. 

Four trains due to travel between Glasgow Queen Street and Edinburgh Waverley before 9am have all been called off due to what the operators are saying is "a shortage of train crew". 

The 6.05am train from Edinburgh to Glasgow, which was due to arrive in the city at 7.17am, has already been pulled, along with the 7am service in the same direction.

The 7.25am and 8am trains leaving Glasgow Queen Street, which were set to arrive before 9am in the capital, have also been cancelled. 

These services are just a few of the more than 40 ScotRail services listed as cancelled on the operators website for Tuesday, April 9. 

These include subsequent departures to Edinburgh from Glasgow at 10.26am, 1.26pm and 4.26pm, as well as returning journeys from the capital at 9.05am, 12.04pm and 3.04pm. 

The service from Helensburgh Central to Springburn at 8.05am has also been pulled due to a train fault.
