Extra carriages will be introduced on early trains between Dundee, Fife and Edinburgh after concerns over “severe overcrowding”.
The move comes after The Courier revealed the packed state of some commuter services was a “significant hazard” for travellers.
North East Fife MSP Rod Campbell had raised the issue in parliament after a key morning service linking Dundee and Fife with the central belt was axed.
Withdrawal of the CrossCountry-operated service had, according to one users’ group, left other early trains dangerously overcrowded.
On Tuesday, ScotRail officials revealed plans to take action to resolve the problem.
A spokesman said, “From today we are operating two additional carriages on its 5.56 service from Aberdeen which leaves Dundee for Edinburgh at 7.08.
“Until now, the service operated as a three-carriage train with 189 seats. The additional carriages offer another 136 seats.”
He added, “We are pleased to be offering more capacity, especially for people boarding at Leuchars and Cupar. This is an interim solution, delivered outwith our usual changes to timetables.”
The spokesman said, “We will continue to monitor the situation and look at a wider range of options to deliver more capacity across the Dundee-Fife-Edinburgh route which has been impacted by the withdrawal of the CrossCountry service.”
Mr Campbell welcomed the development but added he was still hoping for a more “permanent” solution.
“While this move is welcome, I believe that there is more that can be done,” he said.
“A decision by Network Rail earlier this year prevented East Coast Trains from operating a 7am service from Dundee. I have asked the track management authority to look again at that decision, and I am awaiting a response from them.”
