California - Railways
Status
Under the provisions of the US Federal Clean Air Act California has been pre-empted from setting emissions standards for new locomotives or for new or remanufactured locomotive engines. California is, therefore, governed by Federal law for locomotive emissions [1][2]. See US Federal - Railways.
The Californian Air Resources Board (ARB) has, however, established an agreement with two major rail companies obliging them to reduce emissions in or near railway yards in California.
