SIGNALLING problems caused travel misery for morning commuters.

The issues in Edinburgh had a knock-on effect in Glasgow as trains travelling from the capital were delayed and cancelled.

The 9am service was called off due to congestion from the morning signal problems, and the two trains before this were also held up.

Those travelling to Glasgow on the 7.26 service from Airdrie were unable to stop at seven stations including Charing Cross, Partick, Anniesland due to signalling problems.
