If you have the NJ Transit app, just have a ticket already purchased in your account and not activated & whenever you see the conductor/checker checking for tickets (this has happened to me probably 4 out of 100 times I’ve taken the Light Rail), activate the ticket that’s already in your account. I’ve had the countdown timer at over 1 minute and the conductor/checker accepted it and moved on to the next passenger. I think their mindset is “they have some sort of ticket at least, there’s a lot more passengers to check”. Safe travels!
