A top Indian minister has proposed projects worth $130 million project to rid India of the scourge of open defecation and clean up a rail system he described as the world's "largest open toilet", reports said Friday.

Minister Jairam Ramesh told a meeting in New Delhi on Thursday that India, where 130 million households are without a latrine, accounted for 60 percent of the global volume of open defecation.

"This is a matter of great shame, anguish, sorrow, and actually anger," Ramesh, who is also responsible for the Ministry of and Sanitation, was quoted as saying by the Times of India.

The minister unveiled a proposal to spend 1.5 billion rupees ($28 million) to provide 100,000 bio- to villages across India in the next two years.

He also proposed a 5.0 billion rupee project to replace the open-hole toilets on the 50,000 coaches that ply India's vast railway network with bio-toilets over the next five years.

Carrying 11 million passengers a day, Indian Railways "is really the largest open toilet in the world", Ramesh said, adding that his ministry would be willing to pick up half the cost of the toilet re-fit.
