Stevenage is a straightforward, modern station with five platforms, all located at ground level. Think of the layout as a central concourse spanning above the tracks, with stairs and lifts providing access down to the platforms. This compact design makes it much easier to navigate than larger, multi-level interchanges.
The station is primarily a through-station on the East Coast Main Line (ECML), but it does feature a specific terminal platform for local services. Platforms 1 and 2 serve southbound trains heading toward London, while platforms 3 and 4 serve northbound trains traveling toward destinations like Peterborough, Edinburgh, and beyond. These four through-tracks are arranged as two island platforms, meaning you will find trains heading in the same direction on either side of the same platform island.
Platform 5 is the outlier. It is a dedicated terminal (bay) platform located on the western side of the station. This platform is used exclusively for Great Northern services originating from or terminating at Stevenage via the Hertford Loop Line. Because Platform 5 is physically separated from the island platforms, it has its own set of automated ticket barriers at platform level. If you are transferring between Platform 5 and any of the other four platforms, you will need to pass through the main concourse barriers to reach the other side of the station.
For first-time visitors, the main confusion point is often this separation of Platform 5. If you arrive on a local Hertford Loop train at Platform 5 and need to catch an LNER or Thameslink service, allow yourself an extra few minutes to navigate through the barrier lines to reach the island platforms.
Despite this, the station is small enough that connections are generally very quick. If you are relatively mobile, you can easily move between any two platforms in under two minutes by heading up to the overhead concourse and back down. Lifts are available for those with luggage or limited mobility, providing step-free access from the concourse level down to all five platforms. Simply follow the overhead signage once you reach the concourse, and you will find the layout very logical and easy to follow.
