 West of the station is Watling Street, which was raised by some to allow the railway to pass beneath; immediately west of Stag bridge in the direction of Bletchley are points leading onto the disused freight-only railway line toward via the Bletchley flyover.The passenger line and station are protected here by trap points, but they are sited such that any runaway train caught by it would subsequently crash into the bridge.The station was originally built with staggered platforms, a wedge-shaped down platform being near the Simpson Road level crossing to the east.
