My suggestion:- Chopan gomoh and chopan parayagraj will be merged and should run as Dhanbad - prayagraj express . the gomoh part will be extended to dhanbad.
Edited : Rake should be kept in possession of dhanbad division and kept it held for running new train in dhanbad division itself and not in circumstances RAKE should be given to other division in ECR, else ecr will consume it by running somewhere in north bihar in areas like RXL, JYG, SMI, SHC, PNC, DBG, BJU.
