LRT service on Ottawa's Confederation Line will be suspended between Blair and Hurdman stations this weekend for more work on the track's switch heaters.
That eastern section of the line will close Saturday and Sunday. Similar work led to closures over the last two weekends.
Last winter, snow accumulation appeared to cause switches on the eastern leg of the Confederation Line to malfunction, one of the key causes of the delays that beset the transit system.
The Trillium Line has switch heaters powered by propane and natural gas, whereas the newer Confederation Line's were originally electric. The new heaters being installed will be powered by natural gas.
