NOTES FOR MEASUREMENTS: For the purpose of payment against this item, the length of track shall be measured as under :-

1. General: By the difference in the chainages of the length under consideration, as incorporated in the layout plans.

2. Turnouts: The track taking off shall be deemed as starting from the SRJ of the Turnout. 3. Cross-over’s: The length of track shall be taken as the difference in the chainages of

the toes of switches of the two turnouts constituting the crossover.

4. Diamond crossing with or without slips:The two tracks crossing each other shall be measured independently as per note 1 above as though there were no crossing. No extra payment shall be provided for slip points.

5. Dead ends and tops of loops:The lengths for payment under this item shall be up to the chainage of anchor mast of the terminating OHE. 6. Feeders and return feeders from grid sub-station to feeding station: This item will also be applicable independently in case of feeders / return feeders / conductors from grid sub-station to overhead equipment feeding stations or in a case of feeders / conductors running on independent structures (not supporting OHE) along or across tracks. In such a case the length of line to be considered for purpose shall be measured by (a) the distance between the center of gantries of the grid sub-station and feeding stations in case of feeder / return feeders / conductors line from grid sub-station, or (b) by the distance between the center line of the two structures to which the feeders / return feeders / conductors are anchored in case of feeders running along the track if such feeder / return feeders / conductors are running completely on independent structures or (c) by the distance between the center of the two structures supporting the OHE on either side of the first and last independent structure or (d) in case of feeders / return feeders / conductors running along the track supporting OHE. 7.
