Kolkata: The city-headquartered Eastern Railway has achieved two remarkable feats ~ it has fitted the highest number of bio-toilets in train coaches and has carried the highest number of suburban passengers among all the railway zones of Indian Railways in the just concluded 2017-18 fiscal year.

According to an official release issued by Eastern Railway, the zone has fitted as many as 4,335 bio-toilets in train coaches during 2017-18 whereas the target was for 2,800. In surpassing the target, it has achieved the highest ever fitting of bio-toilets in a financial year among all the 17 railway zones.

Bio-toilets work on the principle of decomposition of waste by proliferating anaerobic bacteria, which converts human waste into methane gas and water and this water is disinfected before it is discharged on to the railway tracks.

This is an environment-friendly move that helps keep station premises clean and does not cause corrosion of railway track fittings and fastenings.

Alongside the feat on bio-toilets, Eastern Railway has also occupied the first position both in terms of suburban passengers and earnings among all the zones in Indian Railways in the 2017-18 fiscal year.

ER has carried 1031.48 million of suburban passengers, registering a growth of 3.46 per cent over that of the previous year. The corresponding earning from this went up to Rs 628.93-crore, which is 4.20 per cent higher than the previous year.
