NEW DELHI, Oct. 29 (Xinhua) -- At least three persons were run over by a speeding train in the Indian capital New Delhi, railways officials said Monday.

"Three persons trespassing the tracks were run over by Train no 12446 Bikaner-Delhi express near Nangloi Railway station," a spokesperson for Northern Railways tweeted.

The state-owned Indian Railways is planning to put fencing along all train tracks in the wake of the accident earlier this month when 61 were killed in the northern state of Punjab after a train ran into a crowd.

According to railways data, some 50,000 people died in India after being mowed down by trains while crossing tracks between 2015 and 2017.

The Indian Railways considers anyone coming to train tracks as a trespasser.

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

However, train disasters are common in India as much of the colonial-era rail infrastructure is out of date.

In 2015, the Indian government pledged 137 billion U.S. dollars over five years to modernize and expand the railways.
