Don't Rely on Signals. You should not rely solely upon the presence of warning signals, gates, or flagmen to warn of the approach of trains. Be especially alert at crossings that do not have gates or flashing red light signals. Double Tracks Require a Double Check. Remember that a train on one track may hide a train on the other track. Look both ways before crossing. After one train has cleared a crossing, be sure no other trains are near before starting across the tracks. Yard Areas and Grade Crossings in Cities and Towns. Yard areas and grade crossings in cities and towns are just as dangerous as rural grade crossings. Approach them with as much caution. 2.15.4 – Stopping Safely at Railroad- highway Crossings A full stop is required at grade crossings whenever The nature of the cargo makes a stop mandatory understate or federal regulations. Such a stop is otherwise required bylaw. When stopping be sure to Check for traffic behind you while stopping gradually. Use a pullout lane, if available. Turn on your four-way emergency flashers.
