EFFECT OF HEAVY CARS ON RAIL

The basis for Union Pacific's decision that 125-ton cars on four-axles have exceeded the wheel loads which track can sustain is illustrated. The rail head steel is stressed beyond its elastic limit by such cars and plastic flow ensues. The author says that rail life decreases exponentially as wheel loads are raised.
