Ald-Aly-Muv is fully electrified.
Only problem is that at Muv, only Platform 1 is electrified.
and from Muv to BSB, only one line fully electrified and on second one, work in progress.
So eloco train cannot run from Ald to Bsb, as if suppose, Vibhuti Up 12333 Express is allowed to run on the electrified track from Bsb to Muv, then its counterpart...
more... Vibhuti Down 12334 Express cannot run on eloco from Muv to Bsb as other track between Muv & Bsb not electrified. And thus 100 of electric engines will go to Muv but cannot come back. Similarly 100 of diesel engines will go to BSb from Muv but cannot come back.
Practically, this cannot happen, so till the time other (double one) track not electrifies, eloco will not run from Ald to BSB or beyond and vice-versa.
Second, Ald to Muv, two three trains can do run which have to be cumpulsorily started from/ terminated at Muv Platform 1 only.
isse achchha hai ek do hafte me IR itna sa bachaa hua kaam hi kar le pura.
