Controller (TPC), depending upon the work load. All switching operations on the system are thus under the control of one single person, namely TPC, who is responsible for maintaining continuity of power supply on all section of the OHE. He also maintains continuous and close liaison with the Section Controllers in regard to train operations on electrified sections. Further details regarding Remote Control are given in Vol II of this manual 1.3.2 Communication Facilities All aerial telecommunication lines running by the side of the tracks are replaced with under-ground cables/microwave to overcome the interference caused by 25 kV single phase ac traction. The cables contain adequate number of pairs of conductors for the various types of Railway telecommunication circuits on ac traction. For technical details reference may be made to Indian Railways Telecommunication Manual. In an electrified section it is essential, in the interest of efficiency to provide several independent telephone circuits to facilitate quick communication and to achieve co-ordination between different branches of the Railway. In an emergency several alternate telephone channels will be available for communication should one fail. The various telephone circuits provided in electrified sections are described below briefly :- 1. Train Control/Section Control: This circuit is operated by the Section Controller and is used mainly for controlling train movements within his jurisdiction. It has connections with Signal Cabins, ASMs’ Offices, Loco Sheds and Yard Masters’ Offices. 2. Dy. Control Telephone: This circuit is operated by the Deputy Controller and is used for directing traffic operations in general. It has connections with the important Station Masters’ offices. Yard Masters’ Offices, Loco Sheds and Signal Cabins. 3. Stock Control Telephone This circuit is operated by the Stock Controller and is mainly used for keeping a continuous watch and to maintain control over the movements of wagons. It has connections with Yard Masters and important Station Masters office. 4. Traction Loco Control This is a circuit provided for ac traction and is operated by the Traction Loco Controller who is responsible for movements of electric 7
locomotives and Electric Multiple Unit (EMU) stock. It has connections with Electric Loco Sheds, EMU Sheds, Important Station Masters, Yard, Divisional Officers such as Sr. DEE/DEE, AEE(RS), Sr. DEE/DEE/AEE(OP), Traffic Control Offices, Traction Foreman and important crew booking points. 5. Traction Power Control This is a special circuit on ac traction and is used by TPC for all communications in connection with power supply switching operations and ‘permit-to-work’. It has connections with Station masters’ offices, cabin. Traction sub-stations, feeding posts, sectioning and subsectioning posts, traction maintenance depots, important Signal Cabins, Divisional Officers such as Sr. DEE(TrD), Sr. DEE/OP and Traffic Control Offices. 6. Emergency Control Circuit This circuit is provided to facilitate the traction maintenance gangs and electric train crew to get in touch with TPC with the least possible delay in emergencies. It is also used by train crew in times of accidents for communication with the Control office. This circuit is operated by TPC and is located in the RCC. Emergency telephones socket boxes are provided along the track at an interval of 0.75 to 1 km and also and near the signal cabins, subsectioning and sectioning posts, insulated overlaps and feeding posts etc. Portable emergency telephones are given to maintenance gangs, train crew and station Masters. By plugging the portable telephone into an emergency socket it is possible to communicate with the TPC. 7. Hot Line Communication Hot line communication circuit should be provided between the HQ, divisional HQ traction loco controller and electric loco sheds. These would be provided in the HQ with CEE, CEE/Loco, Dy.CEE/RS, Sr.DEE/RS in the sheds and Sr.DEE/OP in the divisions. 8. Walkie Talkie sets : Every maintenance depots of OHE should have adequate numbers of walkie-talkie sets to be available with them during their normal maintenance work as well as break-downs so that not only effective communication is available at site but also to increase the efficiency and productivity of the work during power blocks. These walkie-talkie sets are to be used primarily for the following purposes: a) To communicate to the maintenance/breakdown gangs/parties that power block has been sanctioned. 8
