Mad link - a collectors item for loco link fans. The ERS-Patna Exp is hauled by an ERS WDM 2 from ERS to MAS though the line is electrified. The loco travels a good 689 km through electrified territory. Why electrification when trains like this run with diesel for hundreds of kilometers under fully electrified territory.
