On 17 December 1840, the line from London reached a temporary terminus at Wootton Bassett Road west of Swindon and 80.25 miles (129 km) from Paddington. The section from Wootton Bassett Road to Chippenham was opened on 31 May 1841, as was Swindon Junction station where the Cheltenham and Great Western Union Railway (C&GWUR) to Cirencester connected. That was an independent line worked by the GWR, as was the Bristol and Exeter Railway (B&ER), the first section of which from Bristol to Bridgwater was opened on 14 June 1841.
