But single wdm 3a has fulfilled this task for years from bsp upto ET . My home is near uslapur railway station . For years , I have seen single alco chuugging between 10.10- 10.20 am daily. TT to same hi hai nearly. speed up to iska hua nahi hai. pehle bhi near about right time ET pahuch hi jata tha. Suddenly kya hua?
