What runs. What comes next.
See what is running, being built, approved, or proposed—without mixing the official national headline with our named-system catalogue.
At a glance

- 02Our table tracks 28 named systems and projects: 21 have passenger service, and their modelled operational lengths sum to 1070 km. This is not the official national total because the scope differs.

- 04Mumbai has the most kilometres currently under construction at 124.1 km, with multiple corridors building simultaneously.
- 05The catalogue currently identifies 588 km under construction. Approved and proposed corridors are shown separately and are not added to that figure.
