The Biden administration has announced more than $1.4 billion in grants to improve railroad safety and boost capacity across the country. Much of the money for the grants comes from the 2021 infrastructure law. The money will fund 70 projects in 35 states and Washington D.C.

The money will supplement what the railroads themselves spend to maintain and upgrade their tracks and equipment. The six biggest freight railroads in the Unites States spend roughly $23 billion every year on those things. But these grants can be especially important for smaller railroads that operate on much tighter profit margins.
