About after Oxford is Moreton-in-Marsh. This was once the southern end of the Stratford and Moreton Tramway. The line then passes the corner of the Roman town of Dorn. The Cotswold Line leaves the Evenlode which drains into the Thames and enters the catchment of the River Severn. The first level crossing appears. The building west of the crossing is a brick works and the neighbouring pits were the site of Jurassic clay extraction for the works. The village to the north is Paxford. The large country house to the west is Northwick Park, former home of Edward Spencer-Churchill and site of a United States Army hospital during World War II and afterwards a centre for Polish refugees. The line the passes the site of station, about east of Chipping Campden itself. From here the line goes into cutting, then the Campden Tunnel under the Cotswold escarpment. In 1851 unrest among the navvies building the tunnel resulted in a riot – the 'Battle of Campden Tunnel'.
