Dataset Description
This dataset details track and roadway mileage/characteristics for each agency, mode, and type of service, as reported to the National Transit Database in the 2022, 2023, and 2024 report years. These data include the types of track/roadway elements employed in transit operation, as well as the length and/or count of certain elements.
NTD Data Tables organize and summarize data from the 2022 - 2024 National Transit Database in a manner that is more useful for quick reference and summary analysis. This dataset is based on the 2022 - 2024 Transit Way Mileage database files.
In years 2015-2021, you can find this data in the "Track and Roadway" data table on NTD Program website, at https://transit.dot.gov/ntd/ntd-data.
In versions of the data tables from before 2015, you can find corresponding data in the file called "Transit Way Mileage - Rail Modes" and "Transit Way Mileage - Non-Rail Modes."
This dataset's 2024 data comes from the NTD as of September 4, 2025.
If you have any other questions about this table, please contact the NTD Help Desk at NTDHelp@dot.gov.
