The course for treatment is just regular medication to keep the condition in control,' Bhushan Singh added.

Awareness is poor about the widely found condition and instead 'having fits or jerks is stigmatised', the doctor said. 'These patients need to be aware that they should not do work near fire, welding or heavy machinery. With medication they can lead normal lives.'

The Lifeline Express has treated as many as 600,000 patients since its inception in July 1991 and carried out general health checks and 81,000 surgeries for cleft lip and polio deformities as well as corrective eye surgeries. Since July it has introduced a dental department on board.

Now with Bhushan Singh's involvement and a regular epilepsy care and awareness service, the train will halt for around two weeks each at destinations across rural Rajasthan, Uttar Pradesh, Jharkhand, West Bengal, Bihar and Madhya Pradesh till March 2010.

The train has seven to eight doctors who interact with around 300 patients a day. There are two operation theatres on the train, while one coach acts as an OPD.

The Lifeline Express covers 10 destinations a year. The train is booked for the next two years.

Vishwen says he came up with the idea to tap India's strong railway network for providing public health care based on what former prime minister Jawaharlal Nehru had said and fondly quotes: 'To serve the poor of the country, make use of the railways. That's what we did taking a modern equipped hospital to remote corners.'

Vishwen said: 'Often, coordinating with government machinery and the local health services is not easy. We need to spread awareness among them before we can expect patients to open up when the train reaches town. For this we have local NGOs and facilitators.'
