Ms Durrand walked down the aisle of a southbound Sprinter at Wick railway station, and tied the knot with John Steven.
The ScotRail worker was not allowed to wed on a moving vehicle under Scottish law, so the train stood in the station until the formalities were complete.
The couple, in their wedding garb, boarded the 12.30pm train at Wick for the ceremony.
Afterwards Deirdre and John, who manages a furniture shop, boarded the sleeper train from Inverness to London for their honeymoon.
Rev John Nugent, from Wick's St Fergus Church, said:"I've done weddings in outside locations in the past, particularly on beaches and in other isolated locations, but this is the first time I have ever performed a wedding on a train."
