Freight trains use the existing loop to allow passenger trains to pass them on the main line. Steam locomotives on special charters that are not stopping in the station also use the loop as a water stop because nearby road access can allow a water tender to reach the line. It also prevents such trains from blocking the main line or a platform at Newbury. All continuing trains using the loop at the racecourse must also travel through the loop on the down platform at Newbury to rejoin the main line.
