Asbestos sheets piled up at Kurla station, which is getting a new roof made of metal

Environment on mind, the railways has begun the process to change the roof at suburban stations. Authorities have started replacing the asbestos sheets with metal ones, which, they say, are lighter and sturdier. Asbestos mineral fibre of all kinds, including chrysotile (white asbestos), has been certified dangerous by the World Health Organization. Saying that getting rid of it in one go is logistically impossible, railways said the process, being done in phases, is gathering pace.
