to achieve a 75% increase in Par to Newquay passenger services through negotiation and cooperation with the Devon & Cornwall Rail Partnership and Great Western Railway. Operation The line is single from St Blazey to Newquay, apart from one passing loop at Goonbarrow Junction, just south of Bugle. It is used by china clay traffic and also passenger trains in the summer, when there is more than one passenger train on the branch. The loop uses semaphore signals. Passenger services Most passenger services are operated by Great Western Railway, including all local stopping services which are all operated by Class 150 units. In the summer on Saturdays, local services are replaced by express services to and from London Paddington with operation of Class 802 units. Until 2020, CrossCountry operated on the line on summer weekends, with trains to and from Northern England. All express services do not call at intermediate stations on the branch line, instead running non-stop between Par and Newquay. In 2007, a daily through service between London and Newquay began running on weekdays in July and August in addition to the two services on summer Saturdays and one service on summer Sundays. This service was also named the Atlantic Coast Express, along with the existing weekend trains to London, which had gained this name in 1987 when InterCity 125 High Speed Trains started serving Newquay. Freight services The eastern section of the line - as far as Goonbarrow Junction - sees a large amount of china clay freight traffic operated by DB Cargo UK with a depot operated at St Blazey. A freight spur connects the line at St Blazey with Par Harbour, passing under the main line from Par to St Austell to reach the harbour. Although originally built as part of the Cornwall Minerals Railway to convey mineral traffic to the harbour, today it is principally used to convey dried china clay from the clay dries at the harbour. Accidents On 25 May 1991 the first train of the day from Newquay to London Paddington derailed in the Luxulyan Valley. The train was formed of a High Speed Train. The passengers were transferred to the rear power car which was then uncoupled and run slowly back to Luxulyan railway station where the passengers were transferred to road vehicles to continue their journey.
