- Railroad Crossing, Wyandotte, Michigan, Detroit, Toledo & Ironton Railroad, October 1925 - Apart from eliminating it altogether, the safest way to protect a railroad crossing is with movable gates. The earliest gates, introduced around 1870, were hand-operated by an employee stationed at the crossing. Automated gates first appeared in the 1930s. Four-quadrant gates completely block off the road, while more common two-quadrant gates block each lane only in the direction of travel.
