UP 800 series Northern Locomotives
UP 800, the original UP Northern class steam locomotive makes a stop at LaSalle, Colorado, for coal. These FEF-1 locomotives had smaller driving wheels than later FEF locomotives. Compared with 844, the driving wheels are 77 inch diameter, versus 80 inch for the FEF2 and FEF3 locomotives.

UP819 leads another Northern class FEF locomotive at the point of a passenger train through Eaton, Colorado.
