Rail bosses are being urged to ensure passengers are not “cut off” from accessing a vital train service.
Passengers in Laurencekirk have raised concerns that they have been missed out by the Aberdeen to Glasgow train, which no longer stops in the village.
There have also been complaints about a reduction in direct services raised by passengers in Stonehaven.
Both communities are increasingly relying on driving to Montrose to hop on a train to the central belt.
West Aberdeenshire and Kincardine MP Andrew Bowie has now written to Scotrail after he was contacted by passengers.
In his letter, Mr Bowie stated: “The introduction of services stopping at Stonehaven between the hours of 0800 and 1730, and Laurencekirk on a regular basis would greatly increase the potential for more people to use the train rather than car or bus.
“I appreciate there are challenges in time tabling however, it does seem strange to have no Aberdeen – Glasgow service stopping at these settlements between those core day time hours.”
Mr Bowie added: “I have been out in Laurencekirk and I have spoken to many constituents who are understandably frustrated about this.
“The Aberdeen-Glasgow service is one of the main rail routes serving the north-east and it is not fair that they are being cut off from boarding at their local station.
“Many will feel they have little option but to take their car – which is the opposite of what the Scottish Government and local council are trying to encourage.”
Scotrail has said there are now almost double the number of daily services in and out of the village, with an increase in local services.
A spokesman said: “The improvements made to our timetable last December were another milestone as we work to provide better services for Scotland’s railway. This was just the first phase of the work we are doing to deliver for our customers over coming year.
“The investment the Scotrail Alliance is making to modernise the railway, introduce new and upgraded trains means we will deliver faster journeys, more seats, and more services for our customers.”
