The National Transportation Safety Board says Metro-North needs to replace thousands of bolts on more than 400 of the railroad’s newest Kawasaki Heavy Industries Rolling Stock Company M-8 train cars. The NTSB released a report earlier this week that stemmed from a derailment in Bridgeport, Connecticut, in May of 2013, that injured dozens of people. The NTSB said the bolts are too weak.

These are the bolts in between train cars that hold two cars together. The NTSB says the bolts didn’t cause the derailment, but their failure made the two-train collision worse.

In December of 2013, an engineer fell asleep while driving a Metro-North train in the Bronx.  It derailed, killing 4 people. 

The NTSB released a report on Wednesday with safety recommendations.  Among those recommendations is that railroads should routinely screen employees who perform "safety-sensitive" functions for sleep disorders.

NTSB Chairman Christopher Hart says they've made the recommendation to regulators of all transportation industries. He says, for example, it’s been helpful for the trucking industry.

Connecticut Governor Dannel Malloy met on Monday in his Capitol office with Metropolitan Transportation Authority Chairman Thomas Prendergast and new Metro-North President Joseph Giulietti.

Governor Malloy says one key decision was made at Monday's meeting. The MTA agreed that any major project conducted on the rail's infrastructure, that could potentially disrupt rail service, will be independently reviewed beforehand.

U.S. Senator Richard Blumenthal of Connecticut and Charles Schumer of New York say the Federal Railroad Administration only has enough funding for 1% of the safety measures they say are needed to make trains safe.
