The Northampton loop is a railway line serving the town of Northampton. It is a branch of the West Coast Main Line, deviating from the faster direct main line which runs to the west. The WCML is a four track line up to either end of the Loop: the 'up' and 'down' fast tracks take the direct route while the 'up' and 'down' slow tracks are diverted via Northampton railway station. Generally, fast express trains run via the direct line, while freight and slower passenger services run via the loop line.

The southern interconnect between the Northampton loop and the direct London–Birmingham main line is at Hanslope Junction, just north of Milton Keynes. The lines continue to run alongside until the two routes diverge north of Roade at the northern end of Roade Cutting. The loop line then runs north east for several miles until it reaches Northampton station. After Northampton, the line heads to the north-west for around twenty miles, until it re-joins the main line at Hillmorton Junction at Rugby, just east of Rugby station.^[1]
