Tip of the Week

A heat order restricting commuter train speeds is issued when temperatures rise quickly from night to day or when daytime temperatures are extreme. These shifts can produce a "sun kink," which causes the track to shift and curves the rails. Normally the stress is contained by the railroad spikes, tie plates, crossties and ballast to resist the side-to-side movement that causes the rails to buckle.
