(Jenna Fisher/Patch) WALTHAM, MA — If you noticed trains sounding off in Waltham more than usual— or at all— that's because Waltham was among a handful of communities that had its status as a "Quiet Zone" revoked. According to a spokesperson at the Federal Railway Administration, during the week of April 26, the federal body determined that city crossings lacked required supplemental safety measures that the city was requested to have going back to 2008, and thus no longer qualified as a quiet zone.
