During the meter gauge era, One end was closed.
So every trains either takes reversal or terminates.
But now even on broad gauge convertion, it's still same like dead end.
Only God knows, why?
They...
more... just could have added bypass line for future long distance trains.
मैंने देखा है बहुत सारे जन्शन पे उलटी दिशा में रेवेर्सल है।
जबकि zyada ट्रैफिक दूसरी दिशा से आती है।
Like Siliguri,Silighat Town, Anand Nagar-Ghughli(UC), Shahganj, Jaunpur Jn,Sasaram, Gajrauala etc.
