Tip: During rush hours, DART trains run as frequently as every 5 minutes; off‑peak the frequency is lower.

Tips & Practical Advice

• Leap Card / Fare Cards: If you're traveling across public transport (bus + train), a rechargeable fare card (Leap Card) may help you save on fares.

• Timetables & Planning: Use the official sites (Irish Rail, Dublin Bus, Go-Ahead) to check live times and service updates.

• Allow buffer time: If arriving via long-distance train or plane, allow time for transfers, delays, and ticketing.
