An alarming new report has found that New Jersey Transit trains have been involved in more than 150 accidents, resulting in $4.8 million in damage to tracks or equipment in the last five years — and that’s to say nothing of half a million dollars that has been spent on settling safety violations, according to a report from the Associated Press.

A total of 183 safety violations were settled by NJ Transit, which included employee drug use to a violation of operating practices. This comes after a deadly commuter train crash in Hoboken, N.J., when a train smashed into a station there, killing several and injuring more than a hundred people.

The railroad administration began an audit earlier this summer after noticed increased incidents in the rail system and found a ton of safety violations. A total of 25 accidents were reported in 2015, and 10 through July of this year, although none of them resulted in any injuries, according to the AP report.

The NTSB is investigating the recent crash, which involved a commuter train smashing through the steel and concrete bumper and plunging into the waiting area in the station. One woman was killed on the platform.

The NTSB has interviewed the train’s engineer, who was also injured in the crash. Authorities still haven’t released — or perhaps haven’t yet determined — the cause of the crash. Investigators have retrieved the event recorder and are downloading speed and braking information. But they’ve been having problems accessing the first car because of the dangerous situation the station remains in.
