Hazardous materials in train tanker cars can be identified by the numbers on diamond-shaped placards displayed on the sides of cars.

Placards can be numbered or have an adjacent orange panel with a number.

“1267” is the hazard identification number for petroleum crude oil.

The small number represents a class – in this case Class 3, flammable liquids.
