Broad Street Station was once owned by the Lackawanna Railroad and its successor, the Erie Lackawanna Railway, while Penn Station was built and owned by the Pennsylvania Railroad. Previously, passengers wanting to transfer between Amtrak and the former PRR/Conrail commuter lines and the former (Erie) Lackawanna commuter lines had to make their own way (usually by taxi or bus) between the two stations. The Newark Light Rail is equivalent to a one-zone bus ride: a one-way ticket costs $1.60 (as of October 1, 2015), and is valid for one hour on the entire system from the time the ticket is validated. A special $0.75 "Underground" fare is available for trips that use only the subway between Warren Street and Penn Station and not the surface portion. Through-ticketing is available for connecting bus routes. Monthly and weekly NJ Transit bus and rail passes valid for one or more local bus zones, as well as transfers purchased on buses, are also accepted. The Newark Light Rail, like most light rail systems in the United States, operates on a proof-of-payment system, in which riders must present their tickets upon request during random fare inspections by police officers, transit workers, or fare agents. Passengers must purchase tickets at ticket vending machines (TVMs) located on station platforms or near station entrances. One-way, round-trip, and ten-trip tickets must then be validated at automated validators located near the TVMs, which stamp the date and time on the ticket for 60 minutes of use. NJ Transit's fare inspectors randomly check tickets on trains and at stations; fare evasion carries a fine of up to $100. On the PCC streetcars, cash fares (exact fare) were paid on board via farebox, except for a brief period starting in October 1999 prior to the introduction of LRVs, when proof-of-payment fare collection was instituted. On weekdays, service operates separately between the two sections. On weekends, service operates jointly. The Newark Light Rail system uses a new-model vehicle built by Kinki Sharyo of Japan. This model is the same one used by the Hudson-Bergen Light Rail system, although the ones used on the Newark Light Rail were built with slight modifications to the trucks and wheels due to the different rails used. Like the HBLR vehicles, the NLR vehicle is a double-articulated vehicle with three sections. Each of the two end sections has an operator's cab at the far end, thus eliminating the need for the vehicle to turn itself around physically in order to reverse direction.
