Chord/main lines refer to which was older/shorter routes right?
Not necessary for electrification!
Eg VM TPJ has chord via VRI(electrified first) and main via MV(electrified later)!
I may be wrong though
please wait...Translate to HindiChord / main lines ka matlab kya hai ki, woh purane / chhote routes hain, sahi?
Electrification ke liye jaroori nahi hai!
Jaise VM TPJ mein, chord VRI se hota hai (pehle electrified) aur main MV se hota hai (baad mein electrified)!
Mujhe shayad galat yaad aa raha hai!
