Publicity film produced by the Pennsylvania RailRoad (PRR) in 1952 showing modern safety features introduced by the railroads such as cab signalling. You'll also see the dragging equipment detector, the "TrainPhone" radio system and locomotive event recorders as well as other technological advances that allow the railroads to run more safely & efficiently.

The PRR was an American railroad founded in 1846. The PRR was the largest railroad by traffic and revenue in the U.S. throughout the first two-thirds of the twentieth century and was at one time the largest publicly traded corporation in the world. At its peak, it controlled about 10,000 miles (16,000 km) of rail line. In the 1920's it carried about three times the traffic (measured by ton-miles of freight) as other railroads of comparable length, such as the Union Pacific or Santa Fe railroads. .
