Trains move on fixed <a href=\"https:\/\/en.wikipedia.org\/wiki\/Rail_tracks\">rails<\/a>, making them uniquely susceptible to <a href=\"https:\/\/en.wikipedia.org\/wiki\/Collision\">collision<\/a>. This susceptibility is exacerbated by the enormous weight and momentum of a train, which makes it difficult to quickly stop when encountering an obstacle. In the <a href=\"https:\/\/en.wikipedia.org\/wiki\/United_Kingdom\">UK<\/a>, the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Regulation_of_Railways_Act_1889\">Regulation of Railways Act 1889<\/a> introduced a series of requirements on matters such as the implementation of interlocked block signalling and other safety measures as a direct result of the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Armagh_rail_disaster\">Armagh rail disaster<\/a> in that year.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">Most forms of <a href=\"https:\/\/en.wikipedia.org\/wiki\/Signalling_block_systems\">train control<\/a> involve movement authority being passed from those responsible for each section of a rail network (e.g., a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Signalman_(rail)\">signalman<\/a> or <a href=\"https:\/\/en.wikipedia.org\/wiki\/Stationmaster\">stationmaster<\/a>) to the train crew. The set of rules and the physical equipment used to accomplish this determine what is known as the <em>method of working<\/em> (UK), <em>method of operation<\/em> (US) or <em>safeworking<\/em> (Aus.). Not all these methods require the use of physical <a href=\"https:\/\/en.wikipedia.org\/wiki\/Railway_signal\">signals<\/a>, and some systems are specific to <a href=\"https:\/\/en.wikipedia.org\/wiki\/Single_track_(rail)\">single track<\/a> railways.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">The earliest rail cars were hauled by horses or mules. A mounted flagman on a horse preceded some early trains. Hand and arm signals were used to direct the \u201ctrain drivers\u201d. Foggy and poor-visibility conditions later gave rise to flags and lanterns. Wayside signalling dates back as far as 1832, and used elevated flags or balls that could be seen from afar.<a href=\"http:\/\/blog.dcsystemservices.com.au\/#facebook\" rel=\"noreferrer noopener\" target=\"_blank\"><\/a><a href=\"http:\/\/blog.dcsystemservices.com.au\/#facebook\" rel=\"noreferrer noopener\" target=\"_blank\"><\/a><\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Railway signalling is a system used to direct railway traffic<a href=\"https:\/\/blog.dcsignallingsystems.com.au\/index.php\/2021\/02\/25\/railway-signalling\/\" class=\"darkbiz-read-more\">Read More<i class=\"fa fa-long-arrow-right\" aria-hidden=\"true\"><\/i><\/a><\/p>\n","protected":false},"author":1,"featured_media":11,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0},"categories":[1],"tags":[],"rise-blocks_total_comments":2,"rise-blocks_categories":[{"term_id":1,"name":"Uncategorized","slug":"uncategorized","term_group":0,"term_taxonomy_id":1,"taxonomy":"category","description":"","parent":0,"count":21,"filter":"raw","cat_ID":1,"category_count":21,"category_description":"","cat_name":"Uncategorized","category_nicename":"uncategorized","category_parent":0}],"rise-blocks_excerpt":"Railway signalling is a system used to direct railway traffic and keep trains clear of each other at all times.
