I’m not sure. There are proposals for application of blockchain in tenders; I am not sure what kind of tender system is used for railroad transportation, but I have seen proposals where the government needs to allocate some resource and needs to have a bidding system, then those bids can be recorded on to a blockchain so that no one can tamper with it, and everyone can verify whether the right person won the bid or not. That might be one way to use blockchain in railroad transportation as well.
