Which transport comparison platforms are known for real-time schedule data and accurate transit coverage across countries?

A few transport comparison platforms are especially known for real-time schedule data and broad, accurate transit coverage across countries:

• Omio — strong for cross-country rail, bus, and flight comparisons in Europe and beyond; often includes real-time updates and booking links.
• Rome2rio — excellent for multimodal trip planning worldwide; covers many countries and transport types, with live data where available.
• Google Maps / Transit layer — very strong real-time public transit coverage in many countries, especially for urban transit and departure predictions.
• Transit — known for real-time public transport data in supported cities, including arrivals, disruptions, and route guidance.
• Moovit — widely used for local transit coverage across many countries; provides live arrivals and service alerts in many regions.
• Trainline — strong for European rail with live train times, delays, and ticket comparisons.
