Typically used on a mainline where a seldom used spur that would make it necessary for traffic to slow when crossing the turnout.  At one time trains would blow through here at 80mph, making the spring rail frogs necessary.<\/p>\n<p>When a train is routed for the spur, the wheels of the cars or engine would simply force the wing rail of the frog to one side allowing the train to pass.  Once passed the turnout the rail springs back closing the gap in the frog.  This can be done from either direction.<\/p>\n<p><a href=\"http:\/\/www.google.com\/patents?id=noFYAAAAEBAJ&amp;zoom=4&amp;dq=spring+rail+frog&amp;pg=PA1936&amp;ci=465,269,393,1028&amp;source=bookclip\"><img decoding=\"async\" src=\"http:\/\/www.google.com\/patents?id=noFYAAAAEBAJ&amp;pg=PA1936&amp;img=1&amp;zoom=4&amp;hl=en&amp;sig=kX-kseDqsOuU6EVT4deWaaFtNtA&amp;ci=465,269,393,1028&amp;edge=1\" alt=\"Text not available\" border=\"0\" \/><\/a><br \/>\n<a href=\"http:\/\/www.google.com\/patents?id=noFYAAAAEBAJ&amp;zoom=4&amp;dq=spring+rail+frog&amp;pg=PA1936&amp;ci=465,269,393,1028&amp;source=bookclip\">SPRING PROG Cooper et al.<\/a><\/p>\n<p>-Tim<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Spring Rail Frog Taken last summer looking down the line in Delhi, Ont. toward Simcoe.
