US Public Transit Guide: NYC, DC, Chicago & Boston

New York City: the subway (MTA)

The only US system that runs 24/7. Since January 2026 the base fare is $3 — pay by tapping a contactless bank card, phone, or OMNY card at the turnstile; the old MetroCard is retired. Tap the same card every time and the 7-day fare cap ($35) kicks in: after 12 rides in a week, the rest are free.

Know the difference between local (stops everywhere) and express (skips stops) — same price, very different travel time. Uptown/downtown vs crosstown matters more than the line color. The subway is safe for millions of daily riders; standard big-city awareness applies — stay behind the yellow line, keep your phone in your pocket on platforms late at night.

Washington DC: the Metro (WMATA)

Clean, quiet, and distance-based. Buy a SmarTrip card ($2, or free in your phone wallet) — it is required for the best fares. As of 2026 the old peak/off-peak split is gone: weekday daytime (5 am–9:30 pm) runs $2.25–$6.75 by distance; weekday evenings after 9:30 pm and all weekend cap at $2.50 no matter how far you ride. That makes weekend sightseeing genuinely cheap.

You must tap in and tap out — the fare is calculated from your entry and exit stations. The Silver Line reaches Dulles Airport (IAD) in about 55 minutes.

Chicago: the 'L' (CTA)

Get a Ventra card (or tap contactless) — 'L' train rides run about $2.50, buses about $2.25, with 25¢ transfers. The Blue Line runs 24 hours to O'Hare (note: rides from O'Hare cost $5); the Orange Line serves Midway. Lines are color-named (Red, Blue, Brown, Green, Orange, Pink, Purple, Yellow) and the downtown Loop is where they converge.

Boston: the T (MBTA)

The subway lines have colors too — Red, Orange, Blue, Green. A CharlieCard (free at stations) brings subway fares to about $2.40 per ride; paper CharlieTickets cost more. The Green Line is actually streetcars that run underground downtown — slow but charming. The Silver Line is a bus, despite the name.

General newcomer playbook

1. Get the card/app on day one — OMNY, SmarTrip, Ventra, CharlieCard. Fares are always cheaper than cash/paper.
2. Rush hours are 7–9:30 am and 4–7 pm weekdays — trains are packed, and in DC/older systems fares used to vary by time. Travel midday or weekends when you can.
3. Google Maps / Citymapper give accurate real-time departures — more reliable than station posters.
4. Safety: sit near the conductor/driver car late at night, avoid empty cars, and keep bags zipped. US transit is statistically safe; petty theft is the main risk.

Transfers and passes

Most systems give you free or cheap transfers within 2 hours when you use the same card — NYC gives a free subway-to-bus transfer, Chicago charges 25¢. If you will ride 3+ times in a day, check the day pass: DC's $13ish unlimited day pass, Chicago's $5 day pass and Boston's $11 day pass usually beat pay-per-ride for tourists. Weekly visitors should compare the 7-day pass against the fare cap before buying.
