Increasing Speeds through Turnouts
Travel through the diverging route of a turnout can produce high lateral forces and accelerations which require slower operating speeds and have adverse effects on ride quality and component life. The study was aimed at finding a low-cost means to reduce lateral forces and accelerations so that safe speeds through turnouts could be increased. Two No. 20 turnouts which have modified geometry, but conventional length and frog angle, were installed and tested. The current activity is to monitor wear and performance and then assess general cost and benefits.
