In order to increase the speed potential of BOXN wagonin CC +6 T +2 T /CC +8 T +2 T configuration, guidelines forconversion of BOXN wagons to BOXNHAM wagons have beenissued to Jhansi and Kota Workshop, who have been allottedRSP for this work. Following this conversion, the BOXNHAM

wagon shall be fit to run at 100 Kmph (in empty) and 75 Kmph(in loaded) in CC +6 T +2 T /CC +8 T +2 T configuration. Speedcertificate of BOXNHAM wagon has already been issued to allzonal railways to process for CRS sanction.

Upgradation of Speed Potential of BOXN Wagon in CC +6 T +2 T /CC +8T +2T Configuration

Railways have been reporting high rate of failures of ACauxiliary motors. RDSO has taken several steps in this regardand issued various instructions from time to time. RecentAnalysis shows that current failures are mainly on account ofinverter. Several measures to mitigate the problems have beenformulated after study.

Modification Sheet has been issued to Railways for itsimplementation. Reliability of small Aux. Motor shall improve.Use of stand by upgraded inverter of DB motor will supportrunning of Fuel Pump Motor.

Central Innovation Council Meeting Held At RDSO

A meeting of Central Innovation Council was held on01.06.2011 in RDSO. The meeting was presided over by ShriV.Ramachandran, Director General/RDSO and was attendedby technical institutions and private entrepreneurs. It ismentioned here that a National Innovation Council has beenset up by the Govt. of India in order to promote innovations.Technical papers were presented by the Faculty of Amity andIntegral University of Lucknow.Amity University put forward theidea of producing bio-diesel from JETROPHA PLANT and byusing Micro-Algae. Use of Nano Technology for making selfcleaning and self deodorizing techniques was also highlighted.Director General of Amity University, Lucknow, Major General

(Retd.) Shri K.K.Ohri offered all sort of assistance to RDSO forfulfilling the objectives of Central Innovation Council. Privateentrepreneurs from M/s.Apna Technology, Bangalore, M/s.Aryan Exporters Pvt. Ltd. and M/s. Mistral also participated inthe meeting. These private entrepreneurs put various ideaswhich can be implemented in Indian Railways such as waysidesystems, on-board systems, monitoring and data acquisitionsystems and workshop solutions etc.

Shri V. Ramachandran, Director General, RDSO in hisaddress expressed the hope of getting benefit out of the ideasgiven by the participants for the betterment of Indian Railways.The meeting was attended by senior officers of RDSO.

Development of Alternative Design of AC Double Decker Coach

RDSO has developed an alternative design of ACdouble decker coach IRDD Mark-II which has reduced coachwidth of 3050 mm below platform level but provide more spacefrom inside by adopting differential width of lower and upperdecks.

RDSO has submitted a detailed report on “ Developmentof Alternative Shell Design IRDD Mark-II for AC Double DeckerCoach” . The report is based on extensive simulation studiesconducted on IRDD Mark-II shell at RDSO for its structuralstrength. The design is validated through FE analysis undervarious loading conditions as prescribed in UIC 566 standards. The report also covers manufacturability aspect of the design.

Development of Ultra Portable Track Monitoring System

At present OMS (Oscillation Monitoring System) is usedas an inspection tool to be run occasionally. In order to providetrack maintenance data directly to maintenance personnel, it isproposed to develop light weight ultraportable MEMS basedoscillation monitoring system employing GPS technology foridentification of location of track features. The equipment to bedeveloped shall be capable of automatic recording of trackacceleration in the route without manual intervention. TheMEMS based accelerometer sensor shall preferably employwireless data transfer to recorder equipment.

Estimate for the work has been sanctioned for Rs.29.96 lac. A MOU has been entered with IIT Kanpur forresearch and development of the prototype. Field Trial with1st stage prototype has been successfully done. Validation ofaccelerometer and FEM analysis of casing was completedduring July 2010. Field trial with prototype of modifiedalgorithm and track parameter determination facility has beendone between LKO-NDLS and comparison of received datawith PC based data is in progress. Meeting with IIT K was heldregarding further development and trials.

Development of H-Type Tight Lock Coupler and Soft Draft Gear forPassenger Electric Locomotives

Railway Board had sought clarification regardingfitment of the newly developed H-type tight lock and soft draftgear in all passenger electric locomotives. In this regard,problem has been examined and guidelines issued to Zonal

Railways and CLW/CRJ regarding fitment of H-type tight lockand soft draft gear on electric locomotives typeWAP4/WAP5/WAP7).
