How is it different in style, technology, fare collection, et cetera...?
Similarities: The Hudson & Manhattan Railroad (PATH's predecessor) was built to the same standards as the IRT—same car lengths and widths as well as same third-rail system. Hoboken Terminal is the only station that identifies the PATH system as a "subway" (the old DL&W-era sign still reads "R.R. T
RAINS AND S
UBWAY")
Differences:
- The PATH system is all tubes and tunnels whereas the NYC system is mostly cut-and-cover
- Currently, the PATH cars are wider than the IRT cars and conceivably would not be able to operate on the underground IRT system (but IRT cars can run on the PATH system without width issues)
- PATH rolling stock adheres to FRA specifications (it's still connected to the general railway network) whereas NYC Subway falls under the FTA (no connections—closed system; only difference is the Staten Island Railway, which is like the PATH insofar as being FRA-governed)
- Some PATH turnstiles still accept cash fares, as well as the Quickcard and MTA Metrocard
- Conductor rides in first and second cars; NYCTA conductor rides in middle of train
- Only subway-era railroad of its kind to cross the Hudson River into New Jersey (connected all the old waterfront terminals to New York except for two, the CNJ Terminal in Jersey City and the West Shore Terminal in Weehawken)
