The Oregon Portland & Pacific (reporting mark, OP&P) is a fictional railroad Class I, completed in 1880, the railroad stretched from Oregon, Washington, Arizona, & Utah. Over the later years of the OP&P began to expand their route by introducing their Long-Distance Trains, The City of Seattle (operated from 1926 through 1971), The Portland Flyer (Operated from 1937 though 1971), and The Utah State Limited (Operated from 1938 through 1971). Unlike N&W, The OP&P Hold steam much longer than N&W and any other railroads Class I. And it was the last 4th Major Railroad to be fully dieselized, which it happened in May 10th, 1964, When the 1980's & 90's roll around, they began to acquiring railroads to expand their route, so in 1985, they acquired Nevada Western Railroad (NW, my railroad), this expanded the railroad's route to Nevada, California, New Mexico, & Texas. In 1986, OP&P acquired Cincinnati, Pennsylvania, Ohio, & Western, or Cincinnati Road for short (CPO&W or CTR, my other railroad). This expanded OP&P's route to Ohio, Kansas, Missouri, Illinois, & Oklahoma. Today the railroad is one of the oldest Fictional Class I Railroad's in operation as of today.
