Answer / rajesh

in pole
one is the main wire and above it is the holding wire for
holding and maintaining tension , it does not have any
electrical function

it is according to electric railway traction standard hence 2
wires are used

Answer / rajesh

electric traction runs on single phase only ,so no 3 phase
question arises .
secondly in the two wires connected to a mast . one wire is
live wire i.e the wire which is touched by train is live
wire carrying 25000volts ac . the other qwire above it is
supporter wire which maintains tension and structure of
catenary ( traction design) . it is nuetral . when electric
train touches the live one ,ckt becomes complete and gnd is
returned to earth through track .this forms basis of track
ckt and block signalling.
