Another class of steam locomotives was the 4-8-4 type. Used on many railways in the United States of America to power freight and passenger service. These dual service locomotives were call northerns on most railroads and others such as the C&O called them Greenbriers. Here is the Frisco Railway version of a Nothern painted in the Frisco Fast Freight paint scheme.
very nice photo of a Reading T1 taking on water while in freight service. The Reading Company built thirty of these 4-8-4 northern class locomotives from 2-8-0 consolidations in the Reading PA shops. Today four of these locomotives survive.
