An SCR after-treatment system for a locomotive engine includes an enclosure defining an exhaust flow path from an inlet to an outlet, the inlet being flexibly connected to an exhaust outlet of the engine, an injector located in the inlet and configured to provide an aerosolized reductant into the exhaust flow path, a mixing tube extending from the inlet into the enclosure towards a back wall of the enclosure; a plurality of catalyst cells extending parallel to the mixing tube; the exhaust flow path traveling through the plurality of catalyst cells between the mixing tube and the outlet, and a side channel located between the mixing tube and the plurality of catalyst cells. The enclosure is configured to create low back pressure and an even distribution of the exhaust flow path across the plurality of catalyst cells.
