Thanx for correction. I keep forgetting the Pfs no.
Thane is now a Unique station on IR where
PF-1,2,3,4 are under DC traction (NZ for 1st and 2nd line is just after Mumbra station when travelling in down direction)
PF-5,6,7,8 are AC (NZ for down fast i.e 3rd line is near Kopri ROB and for Up fast i.e 4th line is near Mulund station...
more... while 5th & 6th is AC till LTT including the LTT yard.)
PF-9,10 are again under DC as these line are of trans-Harbour line.
