The World Trade Center station was also crucial, as that station contained a loop that enabled trains to turn around and reverse direction. New trackwork was installed at a cost of $160 million, which included an interlocking to allow the trains to switch tracks, thus enabling trains to terminate at Exchange Place. While the station was closed, the eight-car-long station platforms were lengthened by two car lengths so they could accommodate 10-car trains. On June 29, 2003, the Exchange Place PATH station reopened, restoring services to Newark and Hoboken. On November 23, 2003, service was restored to the World Trade Center site with the reopening of the World Trade Center station. In February 2006, the Transportation Security Administration (TSA) established a pilot project to test airport-style security screening at the Exchange Place station. In 2012, the station was inundated by of saltwater from the Hudson River, which had overflowed as a result of Hurricane Sandy. The PANYNJ later announced a resiliency project in which it planned to replace the glass revolving doors and windows that surround the turnstiles with a seven-foot-high concrete wall and aquarium glass several inches thick. The project would include in the installation of two Kevlar curtains. In June 2019, the Port Authority released the PATH Improvement Plan. As part of the plan, two additional cross-corridors were to be added at Exchange Place. The construction of the cross-corridors was expected to be completed by 2022. From January 2019 until June 2020, the Newark-World Trade Center route terminated at Exchange Place on almost all weekends for Sandy-related repairs, except on holiday weekends. The truncation was initially expected to last through all of 2020, but ended in June 2020, six months ahead of schedule. Station layout The station entrance is located approximately west of the former, original station entrance. The station features three -long escalators that provide access to the platform level, located beneath street level. Connections are available to the Hudson-Bergen Light Rail at street level. West of the station (railroad north), there are five trackways, two outer tracks for Hoboken, two inner tracks for Newark and one stub-end track connecting each of the Newark tracks. East of the station (railroad south), both lines continue into their weekday terminus. The station has two vestibules, each containing one side platform and one track for trains in a given direction. The platforms are connected through several corridors. There are switches
