Cleveland RTA to repair light-rail signal system

The Greater Cleveland Regional Transit Authority (GCRTA) today will begin signal system repairs on portions of its Blue and Green light-rail lines.

The project, which might cause minor train delays, is expected to take three to four months to finish, agency officials said in a press release.

The signal upgrade is part of a $47 million effort to maintain GCRTA's rail system. Earlier this month, the agency replaced 7,300 ties and improved track structure along its Red Line subway route.

In total, there are 34 stations and 30 miles of one-way track along the Blue and Green lines.
