Here's an ugly stain on Mumbaikars's conscience -- despite several attempts to keep the city's stations clean, data from the railways show that spitting and littering has doubled since last year. Figures from Western Railway (WR) shows that as many as 6,870 people were littering and spitting in March alone -- more than twice the number caught in March 2016 (3,069).
