(m) Steel tapes or metallic tapes with woven metal reinforcement should not be used in
electrified tracks. Linen tapes are safer and, therefore, should be used even though they
are not accurate.

(n) The top of foundation blocks in electrified structures should be kept clear of all
materials.

284 Maintaining Continuity of Track:

1) During maintenance or renewal of track, continuity of the rails serving electrified tracks
shall invariably be maintained. For bridging gaps, which may be caused during removal of
fish-plates or rails, temporary metallic jumpers of approved design shall be provided as
under. The Electrical Department on requisition will provide the necessary jumper.

2) In case of rail fracture, the two ends of the fractured rail shall be first temporary
connected by a temporary metallic jumper of approved design (as shown in the sketch
below). In all cases of discontinuity of rails, the two parts of the rail shall not be touched with
bare hands; Gloves of approved quality shall be used.

3) In the case of track renewals temporary connection shall be made as showed above.

4) In the case of defective or broken rail bond, a temporary connection shall be made as shown
above.

5) Before fishplates are loosened or removed temporary connections shall be made as in sub
section (3) above.
