Appendix-X Proposed Electronics Equipments for Freight Stock 1 of 4 Proposed Electronics Equipments for Freight Stock APPENDIX- X Following electronics equipments has been proposed by RDSO for better utilization and safety of freight stock. 1. EOTT ( END OF TRAIN TELEMETRY) CDU( Communication display Unit) SBU( Sense and Braking Unit) The EOTT system is alternative of Guard and Brake van.EOTT is a system by which it is possible to monitor brake pipe pressure in the last vehicle of train in the locomotive cab. It also helps the driver to apply brake simultaneously from rear of the train. EOTT system consist of two units , CDU( communication display Unit) and SBU( Sense and Braking Unit).CDU is fitted in Driver cabin and SBU is fitted on rear coupler of last vehicle. SBU is connected to the last vehicle BP hose Pipe. CDU connects to SBU through Radio Frequency communication. SBU sends Radio signals at regular intervals and CDU displays BP pressure of last vehicle & other related data. Operation frequency range is 406.5 MHZ. Various functions of EOTT:  Distance measurements in reference to locomotive.  Last vehicle BP pressure monitoring.  Last vehicle low pressure alarm.  Motion status (Moving or stopped)  Marker light status at last vehicle (ON/OFF).  Battery status.  Loss of communication alarm.  Automatic and manual communication test.  Train Emergency application/ Service application braking from rear.  Data logging facilities.

EIMWB( Electronic In Motion Weighbridge) EIMWB installed on Indian Railways, measures gross weight of freight stock during in motion with maximum speed up to 15 kmph. The primary purpose of weighbridge is to check overloading in wagons which damages the track and rolling stock. Electronic in motion Weigh Bridge consist of (i) Weigh rails of length 5.5 m. (ii) Track switches/sensors for speed and wagon type detection. (iii) Control console with electronic cards for implementing track switch logic and receiving signals from weigh sensors for further processing. (iv) A personal computer, a key board & a printer computer directly linked to control console, for operation, viewing and printing output. EIMWB can measure wagon of maximum weight up to 120 T with minimum scale interval of 100 kg. Weighment on EIMWB is governed by Metrological Laws -OIML R -106 and Standards of Weights and measures Rules, 1987.RDSO specification WD-29-Misc-05 lays down the broad technical requirements of Electronic In Motion Weigh Bridges used on IR. 3. Guard Comfort kit (Solar PV module with fittings) Guard Van are used mostly as last vehicles in freight trains & are manned by train guard. Owing to guard vans being part of freight trains, they generally lie unattended in freight maintenance lines/yard/sick lines/workshops. Currently the guard vans do not carry any power generating source and hence no power consuming fittings (light/fan) are fitted inside the guard vans. RDSO has developed functional requirements for Guard Comfort kit (Solar PV module with fittings) to be installed in Brake Vans. The end purpose is to WAGON MAINTENANCE MANUAL Appendix-X Proposed Electronics Equipments for Freight Stock 3 of 4 provide Light, Fan, Mobile Charging Facility inside Guard Van using roof mounted, pilferage proof Solar PV Module along with its associated equipment (Batteries, Light, Fan, Switch, Socket, any other) and necessary connection. The following functional requirements have been prescribed: SN Equipment Technical Requirement 1 Light fitting Table  LED Light (for low power consumption) Mounted (Two  10W (Min) for Table Mounted & 15 W(Min) for fittings) AND Roof Roof Mounted Mounted (One Fittings) 2 Fan Fitting:  8” (Min) Fans, Wall Mounted with manual/auto Wall Mounted swivel arrangement (Two Numbers)  Power consumption 30 W (max)  Self-contained Unit with anti-pilferage arrangement, connectors & other required essentials. 3 Switch board with  USB port for mobile charging Mobile charging  Switch board to incorporate switches needed for point (Two numbers, Light & Fans Wall Mounted) 4 Solar PV Module  Solar PV module of sufficient capacity to operate with all Associated the above tabulated electrical loads for continuous accessories/ operations for min 12 hours, needs to be provided equipment/  The Solar PV module along with accessories such as connections/ wiring battery, inverter (if needed), connectors, junction boxes, switch gears etc should be a self-contained modular unit that can be fitted in either of the locations detailed in 3.2 below.  The Solar PV module and associated accessories should be provided with suitable anti-pilferage devices to prevent chances of theft/damage/loss. 4. RFID Tags on Wagons ( Radio Frequency Identification Tags) The purpose of providing RFID tags on freight stock is to result in Automatic Wagon Identification using Radio Frequency Identification. WAGON MAINTENANCE MANUAL Appendix-X Proposed Electronics Equipments for Freight Stock 4 of 4 RFID tag position on wagon RFID tag Reader Indian Railways has mandated provision of RFID tags on to the wagons being produced w.e.f 2016.It will enable automatic determination of wagon consist and therefore no manual number taking. It will enable automatic identification of wagons for in motion weighbridge and wayside diagnostic systems. Its implementation will lead to a progressive shift from periodic maintenance to predictive maintenance of rolling stock by leveraging Information Technology. WAGON MAINTENANCE MANUAL
