The first monorail in India was the Kundala Valley Railway in Kundala Valley, near Munnar, Kerala. It was a privately owned monorail system, that operated from 1902 to 1908. That year the system was converted to a narrow gauge railway, which operated till 1924, when it was destroyed completely by floods. The Patiala State Monorail Trainways which opened in February 1907 and closed in 1927 was the second monorail system in India.
The Mumbai Monorail, which opened on 2 February 2014 is the first operational monorail in India, since the closing of the Patiala State Monorail Trainways in 1927. Many other Indian cities have monorail projects, as a feeder system to the metro, in different phases of planning.
