Four long distance trains, including those to Okhla in New Delhi, Howrah and Mumbai would be brought under the scheme from December this year, Divisional Railway Manager A K Rastogi told reporters here.
Referring to the proposed 'Swach Sharat cleanliness Campaign' to be launched on October 2, he said the Railways planned to build a water recycling plant to augment water supply for cleaning operations of coaches.
The division also planned to install 10 lifts, including four in Madurai Junction, as some passengers were hesitant to use the escalator facility due to fear.
Besides RO water units would be installed in Dindigul, Palani, Tuticorin, Virudhunagar, Tirunelveli and Madurai.
