Most of the train from Varanasi belongs to NR (Delhi , DRM-LKO) except a few like 12559 and some more.
Now for example for the following trains 14227,14265,12237,14257 and many more.
So for emergency quota where the application has to be submitted.Is it at DRM office LKO or at CCM ,New delhi or there is some provision in varanasi itself.Obviously people from varanasi will find it difficult to get to LKO or DLI/NDLS for dropping the EQ application
