some part it runs in non electriied route like, ,nididavole, ,bhimavaram, ,gudivida, bza hence diesel loco
disel loco consumes more fuel(cost wise) than electrified loco because the diesel loco works on electricity only generated by diesel,
now a days multiple locos coming ehich runs on diesel as well electricity.only lifting pantha required to convert diesel to electricity
these...
more... locos are very limited.
again guntun to bibinagar non electrified track
in the same way hyd to pune which runs on diesel loco in seperate route where traction not there
