In 1883, a northwards extension, the Swindon and Cheltenham Extension Railway, opened from Swindon Town to Cirencester, with further northward extension to a junction with the Great Western Railway's Cheltenham to Banbury at Andoversford opening in 1891, enabling through trains from the Midlands to the south.

This removed the need for M&SWJR trains to run on the GWR lines, though junctions to the GWR line heading both east and west were retained north of Grafton station.

It had a small main building on the down platform (towards Andover), with a large signalbox that controlled what had become a complex junction.

As a whole, traffic on the M&SWJR fell steeply after the Second World War and the line closed to passengers in 1961,[1] with goods facilities withdrawn from this section of the line at the same time.

The station building has now been incorporated into a larger residential house, with the space between the platforms where the track ran forming part of the garden.
