Five months after a fatal train crash severely damaged NJ Transit's busy Hoboken terminal, there is still no prediction as to when the terminal will fully reopen, according to reporting by Larry Higgs for NJ Advance Media. The crash damaged canopies over the pedestrian walkway at the end of the tracks, closing tracks 5 and 6 and separating access to tracks 1 through 4 from the rest of the terminal.  It also requires riders to and from the higher-numbered tracks to take a circuitous detour through the main waiting room to reach the streets of Hoboken, the local bus terminal, and the PATH train station. NJT spokesman Jim Smith declined to predict when the historic terminal would fully reopen, saying only that  "the work has to be approved by many regulators and done with safety in the forefront."  Federal investigators have yet to release a report on the cause of the accident, in which an inbound train failed to stop at the bumper and continued across the pedestrian walkway, stopping only after impacting the terminal structure itself.  A pedestrian died in the incident, and numerous passengers on the train were injured.
