Campaigners say villages surrounding Grimstone in Dorset would be "revolutionised" by a rail service.
A 500-signature petition to create a platform and request stop has been sent to Network Rail, West Dorset MP Chris Loder and Dorset Council.
Petition organiser Jack Bleasdale said: "This is a golden opportunity to give a much-needed public service to a network of villages that are desperate for it. With no bus service and taxi fares to Dorchester costing about £13 each way, there would be sufficient demand to make it work."
