An Australian tourist who had both legs amputated last month after falling on PATH train tracks plans to sue for negligence — and was hit by not one but two locomotives, according to new court filings.

Visaya Hoffie of Brisbane filed a petition in Manhattan Supreme Court against the Port Authority, the MTA and the city seeking evidence so she can eventually bring a negligence lawsuit.

Hoffie, 23, tripped and fell onto the tracks at the 14th Street PATH station in Manhattan around 4 a.m. on Jan. 11 and had to have both of her legs amputated below the knee after a seven-car train ran her over.

Her mom had previously said that another train then pulled into the station 20 minutes later but stopped in time after the driver saw her bright pink top — but Hoffie said in her filing that the second train also hit her.

“After the first train left the station after running me over, I was left on the tracks for another considerable period of time … until a second P.A.T.H. train came along and hit me again,” Hoffie wrote in an affidavit accompanying the petition.

She claims that a series of safety measures failed to kick in leading to the accident.

Hoffie says the station was well lit and where she fell was far enough away from the tunnel entrance for a driver to see her — especially considering her bright pink shirt.

Her court papers also allege that sensors on the first train that were supposed to detect objects on the tracks weren’t working.

If the sensors had “been working I would have been discovered and spared some if not much of the trauma I ultimately endured,” Hoffie said in the affidavit.

The mere fact that she was left for so long on the tracks “is clear evidence of negligence” by the Port Authority, which should have had someone monitoring and patrolling the station, the affidavit charges.

Hoffie, “having undergone several surgeries; is expected to remain confined to the hospital for the foreseeable future,” the court papers say, adding that she also suffered a spinal fracture and a head injury.

She is seeking video footage, photos of the scene of the accident, investigation reports, witness statements and other records to build her case.

Hoffie’s lawyer, Jesse Minc, said: “We are going to vigorously pursue claims against anybody that we find bares any responsibility for this horrible tragedy.”

The Port Authority declined to comment. A rep with the city Law Department said they would review the legal papers.

The MTA did not immediately return a request for comment.
