RAILISA (RAIL Information System and Analyses) is an online tool allowing users to visualise and download data provided by railway companies worldwide
Numerous indicators are available for more than 100 railway companies: length of lines and tracks on the infrastructure network, passenger and freight traffic (e.g. passenger-kilometres and tonne-kilometres), train movements, rolling stock, staff numbers, financial results, etc.
Some of these indicators have been documented since 1995, and the database is updated frequently.
