on the Portpatrick line in 1886-1887, with electric train tablet instruments, and this was extended to the Challoch Junction - Stranraer section in 1887 - 1888. In the 1895 public passenger timetable, the former Portpatrick Railway main line had four trains each way daily; the first down and last up were fast trains, with "Sleeping Saloon between Euston and Stranraer Harbour". The other trains ran only to or from Stranraer (Town), three each way continuing to Portpatrick. There was an additional short working from Newton Stewart to Stranraer (Town) and back. The Whithorn line had four trains each way, most of them having a connection both to and from Garliestown. At this time there were eight short workings each way between Stranraer and Dunragit, calling at Castle Kennedy. There were four G&SWR workings to and from Stranraer over the Challoch to Stranraer section. The Portpatrick Railway in the twentieth century In the first years of the century, the Manson tablet exchange apparatus (referred to as Manson's travelling tablet catcher) was installed on the line, enabling exchange of the single-line tablets at signal boxes at a higher speed than with manual exchange. Acceleration of the fast trains was planned, and the Traffic Manager, Hutchinson, asked of the Engineer, Melville, "I assume that there can be no objection to the inclusive speed of one of our trains being increased from 36 to 40 mph. The road, I take it, is as good as can be found anywhere." Melville replied "There can be no objection at all to the express trains running at the inclusive speed you refer to ..." The acceleration was applied from July 1901. At this period loadings on the express trains was increasing, leading to operating difficulties, and from March 1904 it was indicated that the mail train would run in duplicate. Regular passenger services ceased on the Garliestown branch on 1 March 1903; Millisle was then renamed Millisle for Garlieston and trains reverted to calling at the original Garliestown station. The railway continued to provide excursion trains to Garliestown in connection with steamer excursions until 1935. In 1922 there was a bad derailment near Palnure. When the state of the permanent way was assessed, "the Ministry of Transport was a bit shocked ... so the entire PP&W main line was put under a 45 mph restriction till it could be reballasted and relaid. This was carried out in
