The trains to Watford Junction are northbound and are accessed through a gateway and by going down a flight of stairs, whereas the other platform is southbound and is directed towards London Euston.
This is accessed by crossing over a bridge and also going down a flight of stairs to reach the platform.
There are also Oyster readers at the main entrance at the top of the bridge.
