The typical off-peak service is one train per hour in each direction between Bletchley and Bedford which runs on weekdays and Saturdays only using Class 150 DMUs.

When first opened in 1905 by the London and North Western Railway, the station was a halt serving the small village of Wootton Pillinge, a largely rural community that, in 1897, had become the site of B.J.H.

Following the building of the village, the London, Midland and Scottish Railway renamed the station (which ceased to be a halt in 1928) to Stewartby.

[9] The Stewartby brickworks was connected to the Marston Vale Line via a 2 ft 11 in (889 mm) narrow gauge railway operating on overhead electrification.

One or two daily container trains began transporting 1,000 tons of waste from Hendon to handling facilities at Stewartby.
