The EasternIdahoRailroad(EIRR) is a relatively new shortline operation beginning in late 1993 when it took over operation of two formerUnion Pacificbranch lines inIdaho. The branches are disconnected and run roughly west/southwest from Minidoka,Idahoand north/northeastfromIdahoFalls,Idaho(also therailroad’s headquarters). The history of these lines date back to the late 19th century and were later purchased by the Oregon Short Line. Today the Watco family of shortline railroads based out of Pittsburg, Kansas, owns the Eastern IdahoRailroad, whosebaseof operations is in Twin Falls. Given that the shortline, today sees a significant and growing amount of traffic its future appears to be quite stable under Watco.
