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.
It does get twins as it carries the link for the slip part to Shivamogga. Not always but I have seen it with twins quite often in last 1 year.
It used to not now. Both trains got Seperated like 6 months back. But ya SMET Trains usually Gets Dual locos once in a while don't know whats the purpose.
There's always a shut loco at SMET siding sometimes KJM sometimes ED
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!!
