Just ran across this from my scrapbook: Filed 15:20 EST copyright, Assimilated Press (AP) Massive Chemical Train Wreck Near Lowell Lowell, MA, March 19, 1957--The first 24 cars of a Pennsylvanian RR freight train derailed and pancaked approaching a bridge over the Merrimack River at about 1 PM today. At this time there appears to be no fatalities. The 60-car freight was carrying a variety of chemicals, many of them deemed as hazardous. Authorities say they have not determined if any of the cars are leaking, so they have not ordered an evacuation of nearby residences or businesses. The derailed cars block both the north and south mains between Boston and Portsmouth, and struck two engines on a siding, tipping one on its side. Pennsylvania RR officials said that they hoped to open at least one of the main lines before midnight. At this time, passengers on through trains are being bused between the two cities. Added: 16:33 EST Railroad officials say that the train, traveling at about 35 miles per hour, appears to have derailed on a new guardrail designed to protect the bridge. "I guess it did its job," said district supervisor Pete Nolan. "Except it was supposed to re-rail bad cars, not derail them. It's back to the drawing board."
