In April 2019 President Trump issued an Executive Order directing the Secretary of Transportation to write a new rule allowing specially constructed tanker cars for railroads (DOT-113 tank cars) to ship LNG, i.e., liquefied natural gas (see Here Come the “Bomb Trains” – Trump to Allow LNG by Rail). It took a while, but after a year-long process the final regs are ready, and soon after they are published in the Federal Register, they go into effect. Hallelujah!
