No.
HW Electrification is different issue, which doesnt need MB Electrification!!
Roorkee-Luxar-Nazibabad stretch are Electrified, with sometimes Electric Loco been seen (Till Nazibabad)
If HW would have to be electrified, it would hav done, but its not viable, revenue-wise, as few trains enroute HW-Ambala or HW-MB!!
HW...
more... will be electrified, whn GZB-Meerut-Saharanpur/Roorkee route gets electrified!!
