[EX Q]: Question: Which of the places where the steam railcars were stationed is older? Passage:In addition to the joint railcars of 1903, the London Brighton and South Coast Railway directors asked their Chief Mechanical Engineer, Robert Billinton, to investigate the use of steam or petrol railcars on lightly used services. Billinton died in 1904, before examples could be acquired, but in 1905 his successor Douglas Earle Marsh acquired two steam and two petrol railcars, for comparative purposes with small steam locomotives of the Stroudley A1 and D1 classes fitted for "motor train" or "push-pull" working. The steam railcars were built by Beyer, Peacock and Company and were of a similar design to those supplied by this company to the North Staffordshire Railway. They were stationed at Eastbourne and St Leonards and ran services on the East and West Sussex coast lines. They were both loaned to the War Department in 1918/19 before being sold to the Trinidad and Tobago government.
