We can take a step ahead the campaign of eliminating human scavenger by using some special tanks in trains so that all excreta will be collected in that tank and will be removed from it at regular interval .it ll benefit in two ways 1)it will not lead to filth on the railway track and 2)the waste can be sensibly treated and used for biogas preparation and manure
