CALLS to halt regular overcrowding on Fife trains have been made after an MSP said passengers were "packed like sardines" on a journey from Inverkeithing.

Murdo Fraser MSP raised the issue during First Minister's Question Time at Holyrood after seeing some commuters left on the platform amid the morning rush hour.

He has called for changes after the peak time train travelling from Inverkeithing to Edinburgh only had two carriages when ScotRail had previously promised the problem of overcrowded Fife trains would be improved by May with the plan to “improve capacity” and reducing the use of shorter trains.

“Today, I boarded the 8.11am train at Inverkeithing rail station, bound for Edinburgh, but it was packed like sardines," he said.

"It was so overcrowded that several passengers were left waiting on the platform for the next train, which was due in another 20 minutes, meaning these people would be late for their work.

“You could see there were already many passengers having to stand when this train arrived at Inverkeithing – it was scandalous. At the meeting back in March with Jenny Gilruth, we were told that this ‘short train’ issue would be resolved by May, but it hasn’t been.”

“It is all very well and commendable for ScotRail to announce they will be reducing the price of peak time fares but there isn’t much point if passengers can’t board the train they need. In their response to my office about the debacle this morning, ScotRail have said that due to a train fault, there were fewer carriages available and the train operated with two carriages instead.

"They apologised to me and the other commuters and stated they plan for ‘the majority’ of rail services in Fife to be operated by at least four carriages, but this should have happened by now.

“I raised this with the First Minister during First Minister’s Questions at Holyrood today, and he has promised that the Cabinet Secretary for Transport, Infrastructure and Connectivity of Scotland, will look into this issue and write to me with her findings, and also said a meeting will be arranged between MSPs who represents Fife and the Cabinet Secretary, which I welcome.”

Responding to the concerns, First Minister Humza Yousaf pledged to investigate the issue.

"We have invested significantly in the rail stock in Scotland in the time that we have been in office and I know the previous transport minister held a meeting with MSPs in relation to the issue that Murdo Fraser mentions earlier in the year," he said.

"I am more than happy for the Cabinet Secretary to write to Murdo Fraser and for representatives to meet with Fife MSPs so we can ensure the people of Fife get the service that they absolutely need and require."

Scotrail say the issue on Thursday morning happened because of a fault on one of its Class 158 trains.

Phil Campbell, ScotRail Customer Operations Director, said: “We know that one of the biggest concerns for our customers is busy trains, and we are sorry to any customer who experienced disruption and overcrowding on their journey this morning.

“We’re working hard to deliver the level of service our customers expect.”
