12313 New Delhi-Sealdah Rajdhani Express with WAP-7 met with 12340 Dhanbad-Howrah Coalfield Superfast Express with WAP-7 as well en route to Sealdah and Howrah respectively. The parallel run, or rather call it a thrilling race continued for almost fifteen minutes when 12340 had to slow down for a stop at Mankar.

PS: 12340 was recently upgraded into brand new LHB coaches.
