  • Singnalling for Track Engineers
    November 2018 Indian Railways Institute of Civil Engineering Pune - 411001 FIRST EDITION : NOVEMBER 2018 70/- November 2018 Indian Railways Institute of Civil Engineering Pune - 411001 FOREWORD Indian Railway is one of the largest railway system in the world and spread in wide area. Safety and Punctuality demands up gradation of technology, modernization and adequate knowledge of field officials. It is felt since long to give professional response in track work connected to & dependent on signalling works. Engineering and signalling works when executed especially in yards require presence of each other. Therefore, Engineering officials need adequate technical knowledge about signalling appliances like track circuit, Axle counters and point machines. Instructions regarding track work in proximity of signals are scattered in form of Manuals, various policy instructions/ guidelines issued by Railway Board, RDSO from time to time. A necessity was therefore felt for compiling these instructions on this subject for quite some time. Shri Surendra Kumar Bansal, then Dean/IRICEN, Shri Niraj Kumar Mishra, Associate Professor/Track-1 & Shri Narendra Kumar Meher, Sr. Instructor/S&T-1 have made sincere efforts to fulfil this demand by bringing out this in book form. However, this book need review at frequent interval to keep it updated for authenticity. I hope that Civil Engineers of Railway will find it extremely informative and useful. Pune Ajay Goyal November 2018 Director / IRICEN / Pune PREFACE Safety is the first & foremost criteria in Indian railway followed by punctuality. It is impossible to deal safe running of trains without signaling arrangement. Signals give advance information regarding correct setting of routes and impart pre-warning to Loco pilots.
