Earlier WCAM2 used haul TVC Rajdhani from Vasai to BRC. so loco change was experimented at BSR but at last at brc it need loco change again, cam to wap, so, bsr loco change stopped.
Once,WAP1 was sent with Rajdhani till Panvel that also didnt workout.
Nearest trip shed for diesel as well electric are available like KYN and BDTS but initiative by NR and CRS sanction is awaited
