Adra - Kharagpur section unlike other sections of SER isn't congested. 4-5 pairs of EMUs in prime time can be easily extended. This will ensure cheaper travel for commuters and be very handy for vegetable transportation through vendor car. Thus the Express line-up won't need to stop back to back at GBA, CDGR and SLB. Those who would want to travel in Express trains can easily catch them at MDN or KGP depending on the train.
After Anara Carshed is commissioned, Tikiapara can completely hand over MEMUs to Nimpura and Anara to solely handle more EMUs.
