I've never taken a train anywhere before and need to take an NJ Transit train by myself tomorrow. How do you navigate the train station and find the train number to make sure you get on the right train?
Details vary depending on which station(s) you'll be using. In general, trains are announced on video screens and/or by audio announcements. Video screens are more common at larger stations and list the next several upcoming trains with arrival time, line name and track number. Audio announcements indicate a track number, train number, and time until arrival. At larger stations there may be staff available who can help.
Schedules are posted, in case you're not sure of the exact time or train number. There's also extensive information at the NJ Transit web site and numerous mobile apps that will help (search on "NJ Transit").
