Good find and detailed write up. Few clarifications -Railway tenders are very stringent. If RDSO is involved not sure how can they justify the budget, proposal and acceptance of the same. Past of railway contractors Texmaco, Titagarh, Kalindee has not been good, The only positive side being Government recognizes Railway as key infrastructure and will invest in it. As seen most of the government construction related business are going to NBCC. I would still bet on NBCC to be major beneficiary of Railway platform development though the margins will be linked to mutual monetisation of huge land parcel Railway holds.
