cted bywood coverings. These prevent accidental contact with the railsby human beings and lower animals, and also protect the rail fromshort-circuits with the track. The covering is carried upon the railsupports. 311 214 ELECTRIC RAILWAYS Bonding. The lengths of conductor rail are electrically… … i Fig. 203. Inverted Rail Insulator Mounted on Tie TRACK AS RETURN CIRCUIT When the track rails are used as the conductors, as is usuallythe case, it is necessary to see that the electrical conductivity ofthe rail joints does not offer too high a resistance to the passage ofthe current. For this…
