Staff Reporter,

Motibagh Workshop is working on the design of bio-toilets to get rid of the stench and also pare its weight to help transform Indian Railways into a Green Railways. The bio-toilet unit is one of its kind over Indian Railway established in 2011 to stop discharging of night soil onto the tracks. Informing about the developments, Chief Workshop Manager, Motibagh Workshop, P S Khairkar, said that they have modified the design of bio-toilet and tests are on the new lighter version of the unit.

Bio-toilet technology was developed by DRDO and the technical know how was passed onto Railways which then zeroed on spare space in Motibagh Workshop to establish its manufacturing unit. The next year target to bio-toilets to be supplied all over Indian Railways is about 3,000, Khairkar informed the newspersons during the interaction on Tuesday.

To cater to Railways, Motibagh Workshop is doubling the capacity of the inoculum mixture plant, the chemical helps to convert the night soil into methane and also purifies the water in the bio-tank.

To a question he said instead of p-trap now S-trap would be attached to the toilet seats that connects the bio-toilet beneath the coaches as this would eliminate the stench inside the toilets. A ball seal in P-trap would get broken due to which the sullied water used to flow back causing the stench which put question mark on the efficacy of bio-toilets. Also Khairkar said a prototype of new bio-toilet that are 1/3rd of current lot being manufactured across country is being tested at Bilaspur Division. The new bio-toilets are smaller in size and also lighter and that would result in savings and also reduce overall tear weight of the bogies. Current bio-tanks weight about one tonnes and fitting it underneath the bogie is quite a complicated task.

He informed that right now Workshop has one tank to produce inoculum, a special bacteria that plays key role in degradation of night soil inside the bio-tank, and two more tanks are being installed to cater to increasing need of Railways. The one tank presently has capacity of one lakh litres storage.

Work has begun at Motibagh Workshop to erect assembly

line for undertaking periodic overhaul (PoH) of Broad Gauge coaches of South East Central Railway (SECR), Bilaspur Zone. The Rs 84 crore project is expected to be completed by February 2019, informed CWM P S Khairkar. The project was approved way back in 2012 but since then nothing moved and got included in Workshop Modernisation programme of year 2016-17.

The workshop used to mainly cater to Narrow Gauge coaches PoH and with SECR going in for conversion to BG the fate of Motibagh was in balance. Currently coaches
of Bilaspur Zone are dispatched to Sriperumbudur for PoH
and in the process of travel much of time gets wasted and hence it was decided at Board level to have one PoH facility in Central India.

The employees’ strength if Motibagh Workshop is currently 550 and it is also catering to PoH of wheel assembly of BG coaches. To a question Khairkar said keeping in mind that ICF coaches are being phased out, the Motibagh Workshop PoH would able to undertake PoH of LHB type coaches also.
