Railway passengers using the Marston Vale Line have been given a boost as the service will start running from platform 5 at Bletchley Station.
After December 14 only four Bedford-bound services will still depart from platform 6, which has no lift access and limited shelter.
The Bedford-Bletchley Rail Users’ Association (BBRUA) said the change would be a particular boost for elderly and disabled passengers.
Chairman Richard Crane said: “This is a big improvement as it means that most Marston Vale Line passengers will no longer have to climb or descend the steep, uncovered steps to and from platform 6 which have proved such a disincentive to elderly and disabled from using the service.
“Passengers will now have access to large heated waiting facilities, and passengers who regularly change onto London-bound trains won’t need to use the stairs or lift.
“As recently as April we were told that this change was not possible due to conflicting train movements. We disputed this, and with the help of Passengers Focus and rail users who have complained the combined pressure has worked.”
The only services which will run from platform 6 from December 14 will be the 7.32am, 10.05am, 1.01pm and 8.01pm.
A London Midland spokesman said: “We have been trying for a long time to make this happen. We hope that in time all services will run from platform 5.”
