Railroad spending plans and hoped-for growth. The evolution of a higher-speed rail project. Rolling stock data. The crude-by-rail rule. Millennials mulling rail as a career. The Canadian Pacific-Norfolk Southern thing. PTC (still). Amtrak (always). These are just a few of the topics that piqued the interest of Progressive Railroading readers this past year, as noted in my January column, "14 from '15." As ever, your tastes are eclectic and run the rail — no, beyond rail, because rail connects bigger-picture dots — gamut. We'll continue to follow these stories wherever they lead. As ever, thanks for reading.
