I tried looking it up on the NJ Transit website (note: not PATH), but there is no information about the Weekly Pass' price. I downloaded the NJ Transit app and Weekly Passes for Rail are not sold there. Does anyone know the price and site the source please?
NJ Transit weekly passes are not unlimited systemwide passes. Rather, they offer you unlimited rides only between two predefined stations along a particular line (or combination of lines). In addition, they include a free transfer to lite rail lines in Newark and Hudson/Bergen counties and single-zone NJ Transit busses for last-mile connections.
Because of this, the price of a weekly pass varies wildly depending on what stations you are riding between. For example, Hazlet to NY Penn Station is a 133 dollar weekly ticket. Secaucus Junction to NY Penn, by contrast, is 38.50.
To find the fare for your particular route, on the NJ Transit Website, click the "schedules and fares" link at the top left and select the two stations in which you're interested. You'll see the price of a single ride, ten-trip, and weekly and monthly passes listed at the bottom of the page, under the train schedule.
I found this information in the NJ Transit Rail website:
Weekly Passes: All weekly rail passes valued at $18 or more are valid for one-zone bus trips and may be used on any light rail line.
