The Baltimore and Ohio Railroad was chartered in 1827 and grew to be one of the largest passenger railways in the United States, often by acquiring other, smaller railroads. In Cleveland the B&O purchased two local companies, the
Cleveland Lorain & Wheeling Railroad and the
Cleveland, Terminal & Valley Railway in 1915. From 1915 until 1962 the B&O provided overnight
sleeping car service between Baltimore and Cleveland on the
Cleveland Night Express. After June 1934, the
Cleveland Night Express used Cleveland's
Union Terminal as its passenger station. At times in this period, the train was called the
Baltimore-Washington-Cleveland Express westbound and
Cleveland-Washington-Baltimore Express. On February 7, 1956, the train had four passenger cars overturn in a sudden rockslide near
McKeesport, Pennsylvania, no deaths occurred with only one injured. ==Decline and end of the train==
