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.

Question: Of the two referees for the match between Shawn and Bulldog, who has worked in wrestling for the longest amount of time? Passage:The main event of the night featured WWF World Heavyweight Champion Shawn Michaels defending the title against the British Bulldog. Just before the match began, as scripted, Michaels was served a summons from Bulldog's storyline attorney Clarence Mason. It stated that Michaels was a defendant with the charge of "attempted alienation of affection" due to the allegation of him making advances towards Bulldog's wife (storyline and real life) Diana Smith, therefore causing strain in their marriage. The timing of the subpoena by Bulldog's camp was an attempt to throw Michaels off his game, giving Bulldog a better chance of winning the championship. During the match, as part of the script, Bulldog accidentally ran into referee Earl Hebner, knocking him out for a period of time. A replacement referee (Mike Chioda) continued the match. Shawn Michaels performed a German suplex into a pinfall combination on Bulldog. By this time, the original referee had regained his senses, and both referees counted the pinfall. Both wrestlers had their shoulders on the mat as Chioda counted Michaels' shoulders down, while Hebner counted Bulldog's down. Due to both wrestlers being pinned simultaneously, the match was ruled a draw and Michaels retained the WWF Championship.
