The Trona visits Philly. I didn't think these things could lead. Perhaps they can't, as the crew stopped to turn the power as few minutes later.
A SD45-2 body is a sweet catch this day in age!!! This is an ex-Trona Railways SD40M-2, nee ATSF SD45-2. Helm dubbed this locomotive as a plain SD40-2 by the stencil under the window.
