Facebook(HOBOKEN, N.J.) — Thomas Gallagher, the man at the controls of the NJ Transit train that plowed into a station Thursday, is a married father and veteran engineer who has worked in the rail industry for almost three decades, officials say.

Authorities say Gallagher, 48, is cooperating with investigators after Thursday’s rush-hour crash in which the commuter train, traveling at high speed, slammed through barriers and into an interior wall at Hoboken Terminal in New Jersey. The crash killed one person and injured more than 100 others.

Gallagher has been released from the hospital after being treated for minor injuries. He tested negative for alcohol and drugs after taking a blood test, a law enforcement official told ABC News. The testing was conducted as a routine part of the investigation as officials examine factors that could have led to the crash. The condition of the train track and whether Gallagher was fatigued are just a couple of factors being considered.

Gallagher, who lives in Morris County, New Jersey with his wife and teenage daughters, has been employed by NJ Transit for 29 years, according to a spokeswoman for the National Transportation Board Safety.

According to what appears to be his LinkedIn page, Gallagher attended Fairleigh Dickinson University in Teaneck, New Jersey, from 1986 to 1990. He listed his profession on LinkedIn as “loco engineer” for NJ Transit, using the abbreviation for locomotive.

The National Transportation Safety Board is investigating Thursday’s deadly crash along with the Federal Railway Administration. As is standard procedure, investigators will look into all possible causes of the crash. However, a senior official briefed on the crash told ABC News that they do not suspect sabotage or foul play.

The NTSB told ABC News it has not yet interviewed the engineer, though they have requested to do so, along with other crew members.
