A westbound BNSF train thunders through Tuscor, Montana, as another autumn day turns to night on October 1, 2020. The train whooshes past bringing cooled air off the Clark Fork with it, making it even colder than it was before the train showed up. With MRL’s commitment to PTC installation, it’s hard to say how long the cantilevers and seachlights will last that still guard sidings at some locations on MRL’s Second and Fourth Subdivisions.
