Lalu started the tradition of not increasing fares. Only one RM tried to increased the fares after Lalu, Dinesh Trivedi who was then promptly removed by his own party chief Mamata. Other RMs do not want to meet this fate so they are increasing fares through backdoor. Unlike what many people think, Lalu was one of the worst RMs. Mamata was way better than Lalu as RM. Even Nitish was better. Lalu also started the SMB in GRs which is now finally removed. He had the idea of putting SMB in all trains, thankfully he was removed as RM before he could implement this. In NDA, Suresh Prabhu and Piyush Goyal were decent RMs. Ashwini isn't the right guy, more of a technocrat.
