Extreme summer heat can cause major delays for GO Transit lines. Here's how track specialists are helping reduce, if not eliminate altogether, those delays.

During prolonged periods of temperatures of 30°C and higher, GO Transit steel tracks can become stressed and expand, leading to bends in the track known as sun kinks. These kinks are one source of heat-delays, as they make it unsafe for trains to run over them at high speeds and can further damage the track. That’s why slow orders in extreme heat are common practice.

Metrolinx, the company behind the GTHA’s Go-Transit rail infrastructure, combats heat-delays in a number of ways. Watch the video above to find out how.
