Odisha may help fulfil the phr demand between rou-tata..
I think BMPR-TATA-ROU will be more than 200 km, as per the present concept they will have to put an ICE or name the MEMU as BMPR-TATA and TATA-ROU, MEMU RSA.
But in SER IRTTC the demanded MEMU is somewhat like: HTE-ROU, ROU-TATA, TATA-BKSC RSA. In other direction its like: BKSC-TATA, TATA-ROU, ROU-Birmitrapur-ROU, ROU-HTE. So already a TATA-ROU MEMU is there in agenda, where BMPR route is not touched.
Tata-ROU Tripling must be over by the end of this year, but BNDM-HTE Doubling will be completed in 2024!! If they will wait for everything to be completed to introduce the MEMU as it will have RSA, then wait will be very long.
