Carry enough cash to make purchases where there is no ticket agent, and be sure to use an ATM card instead of a credit card to withdraw cash at a bank -- the card will work even if it doesn’t have a chip -- so you avoid extra charges associated with a cash advance. If you’re interested in switching to a smart-chip card, you could sign up for one that offers dual activation -- both a stripe and a chip.
