NEW DELHI, June 10 (Xinhua) -- A passenger train derailed in the western Indian state of Maharashtra early Sunday morning, railway officials said.

"Three coaches of the Mumbai-Howrah Mail train derailed near Igatpuri in Maharashtra. No casualties were reported in the mishap," Central Railway spokesperson Sunil Udasi told media.

The incident disrupted railway traffic in the area for some time. "Some 12 trains had to be cancelled," another official said.

A probe has been ordered into the incident, he added.

The Indian Railways is one of the world's largest train networks, criss-crossing the country from north to south. It operates some 9,000 passenger trains and carries nearly 23 million passengers every day.

However, train disasters are quite common in India as much of the colonial-era rail infrastructure is out of date. A number of people are killed in train accidents, mostly derailments, across the country every year.

In 2015, Indian Prime Minister Narendra Modi's government pledged 137 billion U.S. dollars over five years to modernize and expand the railways.
