The Department of Infrastructure has revealed details of a special birthday party next year.
The Manx Electric Railway will celebrate its 125th anniversary in 2018 and Isle of Man Railways says it's already planning a number of special events.
The MER first ran in 1893, and the railway still operates the original trams between Douglas and Ramsey.
Isle of Man Railways says it'll run three number 1 trams at Laxey station - from the MER, Snaefell Mountain Railway and Douglas Horse Trams.
There'll also be a cavalcade of MER trams through Laxey, and the railway will turn back the clock to operate to the 1975 timetable for a day.
The events take place between September 1 and 8 next year.
On Facebook, Isle of Man Railways says it'll announce other anniversary events in the near future, including open days, photography events and photographic tours.
