"State and federal teams examined 445 crude oil tank cars, approximately 128 miles of track and 66 switches as part of these inspections and uncovered and addressed four critical defects and 91 non-critical defects," the statement read on Monday.
The three critical defects were found along rail systems in mid-New York and included two gauge malfunctions and a worn tread on a switch transition device, all of which was repaired immediately.
The inspections were conducted as part of initiative that was launched in February 2014 to protect New Yorkers from the potential dangers associated with the transport of crude oil by freight rail companies, Cuomo’s office added.
"These inspections are critical to helping ensure these rail networks remain safe and that New Yorkers can work, travel and live near them without anxiety," Cuomo said.
In July, a train carrying crude oil derailed and spilled over 35,000 gallons of crude oil in the US state of Montana.
In February 2015, two other oil transportation trains derailed, bursting into flames in West Virginia and rural Ontario, Canada.
The crashes caused public concern and renewed a debate about the safety of the oil rail traffic.
In 2013, more than 1.15 million gallons of crude oil were spilled from transport trains, more than the previous four decades combined, according to the US Department of Transportation.
