Method of Crossing – overhead line or underground cable: 7.1 For tracks already electrified or to be electrified in the foreseeable future: All low, medium and high voltage upto and including 11 kV crossing(s) shall normally be by means of underground cable(s). While for voltages higher that 11 kV, crossings may be by overhead lines or underground cables, the use of underground cable to the extent possible would be advantageous, particularly for 22 kV and 33 kV system. 8. Protection of Communication Lines: 8.1 The crossing shall in no way interfere with or endanger any Railway communication lines. Approval given by the Railway for placing of any crossing shall not be construed as affecting in any way the requirements of the Indian Post and Telegraph Deptt.

All such works shall be carried out under the direct supervision of the Railway. 9.2 The crossing shall always be maintained in a state of good repair so as to reduce hazards to life and property. It shall be inspected by the Owner at interval not exceeding 12 months in order to determine its fitness for service. Defects, if any, noticed or as pointed out by the Railway shall be rectified by the owner expeditiously. The decision of the Railway in regard to defects noticed and rectification(s), if any, to be done by the owner shall be final and binding on the owner. 9.3 The crossing span as well as two adjacent spans on either side of the overhead line crossing shall be kept free by the owner from any trees and branches which, if they fall on these spans, would foul with the overhead line. The growth of bushes and wild vegetables shall not be permitted on either side of the overhead line for the same reason. 9.4 Where galvanized steel structures support the crossing span, they shall be maintained free of rust, corrosion, etc. 9.5 If at the instance of the Railway, the crossing is to be shifted or modified or dismantled, the work shall be carried out by the owner at the cost of the Railway. However, in those cases where the need for such works on account of Railway’s anticipated developments/requirements was foreseen in time and the owner had agreed in writing prior to the construction of the crossing to meet the cost of such works. Such works shall INDIAN – RAILWAYS -AC TRACTION MANUAL VOL II PART II be carried out on a priority basis by the owner within a fixed schedule, as mutually agreed upon between the owner and the railway and to the satisfaction of the electrical Inspector. The Railways shall have the right to claim compensation for any loss and/or inconvenience caused if there is avoidable delay in completing the works. 10.
