WIDE-GAUGE RESEARCH LEADS TO A NEW STANDARD ON UP

Following research on the causes of wide gauge, Union Pacific has adopted as standard a 16-inch tie plate with a 1:30 cant. Gauge widening is a problem common on high-speed,heavy-duty mainline track and this phenomenon was investigated on UP as part of the industry's Track Train Dynamics Research Program. Tie-plate cant varied from standard 1:40 down to 1:14. The 1:30 design finally chosen is to reduce the incidence of rail rollover and to reduce overloading on the gauge side so that the wear pattern was down the center of the rail.
