Following that unfortunate tragedy, it was said that the manufacturing standards for tank cars should be changed, really improved. So there is already a consensus on that. The effort now should be for the industry to put those new criteria into effect as quickly as possible. The technical knowledge of the issue is understood.
It must first be shared with those involved in regulation and with other parties so that it is acceptable to all. Yes, the industry has concerns, but the users, the consumers, the people who want safe products around them, have concerns too. I have no particular expertise in the railway industry, but I know that there must be consensus in all the areas where you hope to establish a standard.
