From Central Railways Special Visitor 😍AJNI WAG9H😍 to Ballari Jn.
After tss got completed electric locos have already started to dominate this route
Single Line Crossing | Twin KJM WDP-4B with #20030 in lead with 56913 SBC-UBL Fast Passenger waiting at BSN for 20652 TLGP-SBC Intercity Express to cross.
Dual Loco could be coz of Steep Radiant which may serve as banker to Freight and sometimes are used for Passenger Service!!
Twins cant get decoupled and run as split Loco for split rake for slip & regular rake (until they arnt coupled and run as different unit)!! Its easy to attach/detach one Rake with other (as in Freight Python Rake), without disturbing loco (to minimize hassle & time)!!
To decouple Locos (and to recouple when slip gets attached), is a complicated process (carried out at Loco Shed) & usually Twins remain stable for long period and attached to train, as per availability!!
Is the twins is a new loco
Because whenever a new d loco enters service the first run will be with an another loco attached to it
Both will be on duty
Twin locos are provided by KJM/UBL now a days to reduce idling time at shed
