With a focus on upgrading passenger amenities, Indian Railways is planning to equip the entire fleet of AC coaches with aircraft-style bio-vacuum toilets at an estimated cost of Rs 1,500 crore.
After installing bio-toilets in over 60,000 mainline coaches, the railways has taken a further step of providing bio-vacuum systems in all LHB (Linke Hofmann Busch) coaches.
The retrofitment of all coaches of premier trains including Rajdhani, Shatabdi and Duronto with bio-vacuum toilets are to be carried out as part of Make-in-India initiative, said a senior railway official.
Taking a lead in the bio-vacuum toilet installation, Northern Zone is in the process of equipping 714 AC coaches of premium service with the system.
While 600 coaches are already being equipped with the bio-vacuum system during the lockdown, retrofitment for the rest of coaches are underway, it is learnt.
