BNSF rails are used for mass transit in Chicago. They're also used for Amtrak routes. BNSF has historically been the freight railroad most friendly to passenger rail. Unlike Union Pacific and CSX, they aren't antagonistic to Amtrak, and make an effort to give the passenger trains proper right-of-way. An interesting note about the Metra service in Chicago is that it is operated by the BNSF under contract with the State. So the Metra conductors on the BNSF line are actually BNSF employees. It is one of the busiest and most productive lines Metra operates. It's also one of the most professional.
