No the statement I make is out of the FHWA manual for highway/railroad crossings.http://www.fhwa.dot.gov/tfhrc/safety/pubs/86215/86215.pdf Appendix D which is on pdf. page 248 or manual page 241 depending on how you look it up. or the chart can be seen better here with page 2 column 1 is for stop signed crossings http://www.wsdot.wa.gov/TA/ProgMgt/Grants/Sight_Eng.pdf <br /> <br />Foot per second distance is 1.4666 times mph speed. Or miles per hour times 5,280 divided by the number of seconds in a hour which is 3,600. <br /> <br />A 80 mph train is going 117.328 feet per second. IF the whistle post is 1/4 mile (1320 feet) which different states vary, it takes 11.25 seconds for the train to reach the crossing from the whistle post. At 1 mph it takes a 65 foot truck starting 6 foot from the tracks 52.5 seconds to clear the kill zone of the train. Gates and lights are required to give 26 seconds warning, 20 with the gates all the way down so there are 15 seconds of warning missing at all passive crossings with 80 mph trains.
