A months-long project that will involve grinding Metrolink’s entire system of rails begins Friday night.
It’s the first time since the late 1990’s that Metro has done the grinding on its light rail line. Metro spokeswoman Dianne Williams says it will make the track more smooth and improve riders' experience.
"It needs to be done periodically. It simply extends the life of the rail, and that's a big investment in the track," Williams said.
The work will be done at night, which means people may see bright red sparks where the grinding of metal on metal is being done.
