What is this train doing?

It’s carrying snow from Fairbanks, Alaska, to Anchorage, for the start of the annual Iditarod dog sled race.

Anchorage, it seems, didn’t have enough snow to cover its streets for the start of the race, which runs 1,500 km. to Nome.

No snow in Anchorage in March. But climate change is nothing but leftist myth.

At least they have  railway.
