A monorail runs on a single elevated beam rather than a conventional two-rail track. That makes it a compact, fully elevated mode, useful on dense urban corridors where road space is tight. In India the flagship is the Mumbai Monorail, the country’s first and so far only system. This page covers monorail in India: how the technology works, where it runs, and the latest developments.
What a monorail is
A monorail vehicle straddles or hangs from a single guideway beam, usually on rubber tyres. The result is a small footprint, a tight turning radius and a quiet ride. Most modern systems, Mumbai’s included, use the straddle-beam design, where the train sits astride a slim concrete beam. On capacity it sits below metro. It works well as a feeder or on medium-demand corridors, but it cannot match a metro’s throughput, which is why cities weigh it carefully against light metro and Metrolite.
Mumbai Monorail: India’s first
The Mumbai Monorail is India’s first and only monorail, running 19.54 km between Chembur and Sant Gadge Maharaj Chowk (Jacob Circle) under the Mumbai Metropolitan Region Development Authority (MMRDA), serving eastern and central Mumbai neighbourhoods that the metro and suburban rail do not reach directly. It opened in phases from 2014. Passenger services have been suspended since September 2025 for a full CBTC signalling and rolling-stock overhaul; the upgraded system was safety-certified in June 2026 and resumption is pending final safety-net installation. Its full profile — route, timeline and current status — is below.
Why monorail stayed a niche in India
After Mumbai, several cities studied monorail lines, but most were dropped in favour of metro, Metrolite or Metro Neo. The reasons repeat: lower passenger capacity, higher per-km cost than first expected, limited interoperability and awkward evacuation. It remains a sensible choice for specific feeder and medium-capacity routes, and we track every proposal as it develops.

Frequently asked questions
Which is India’s first monorail?
The Mumbai Monorail, India’s first and only monorail, running between Chembur and Sant Gadge Maharaj Chowk (Jacob Circle). Passenger services are currently suspended for a safety and signalling upgrade.
How is monorail different from metro?
Monorail runs on a single elevated beam with a smaller footprint and lower capacity. Metro runs on a two-rail track and carries far more passengers per hour.
Why don’t more Indian cities have monorail?
Most proposed lines were dropped in favour of metro, Metrolite or Metro Neo, mainly because of monorail’s lower capacity and higher-than-expected costs.
