Research projects boost diamond service life

摘要

Crossing diamonds are high-maintenance items that cost railroads dearly in terms of budget dollars and delayed trains. That's why they are the focus of major research efforts at the Transportation Technology Center, Inc., Pueblo, Colo. "Crossing diamonds and turnouts are weak links in the track structure in terms of reliability and maintenance costs," said Semih Kalay, TTCI's assistant vice president research and development, at the 2000 AAR Research Review in March.
