Yes i totally agree with u... SR is far better than NR in terms of electrification... SR ne electrified line ka pura ek circle bana liya h..
Like -----> Chennai - Erode - Coimbatore - Trivandrum - Nagercoil - Tirunelveli - Madurai - Tiruchirappalli - Chennai
But Northern railway ka na abhi tak Rohtak - Jind - Jakhal - Dhuri - Ludhiana ka circle bana aur na hi Ghaziabad - Meerut - Muzaffarnagar - Tapri - Saharanpur wala circle bana :-(
