Same reason as the "German Wings" Airplane crash. A Despondent Homosexual felt the need to kill himself and his passengers, so he increased speed to crash the train.
While there has been a lot of speculation as to the sexual orientation of Andreas Lubitz, nothing in his background really proves that he was gay or that gayness had anything to do with why he decided to crash the plane. He was however bat sh!t crazy and with prior serious episodes of depression and feelings of self aggrandizement and flights of fantasy and phycosemantic illnesses which should have alone have kept him from flying. There are a lot of bat sh!t crazy people in this world and FWIW, and not all of them are gay. Just saying.
