In addition to the Pennsylvania Schuylkill Valley, the Penn-sylvania made one other addition to its mileage in the anthracite fields, in the purchase and completion of the “North and West Branch Railroad Company”, which had a charter to build a line from a connection with the Sunbury, Hazleton and Wilkesbarre (PRR) at Catawissa Junction, east along the Susquehanna to Wilkes-Barre. This company had been organized in 1872, and its line partly constructed.

On February 1, 1867, the C&A and NJRR were informally joined as the United New Jersey Railroad and Canal Companies (UNJ). The Pennsylvania Railroad (PRR) approved a lease of the UNJ on May 15, 1871, and the UNJ approved May 19. On May 18, 1872, the C&A, D&R Canal and NJRR were consolidated, forming the United New Jersey Railroad and Canal Company.

The north-south Puget Sound railroad route, long awaited and dreamed of, finally forged ahead in 1890 when James J. Hill (1838-1916) purchased the New Westminster and Southern Railway. That same year he created the Seattle & Montana Railroad to be the second section of the three divisions set up by Hill's backers on the north-south route. Hill purchased the Fairhaven & Southern Railroad that ran from Bellingham Bay to the Canadian border (originally built by Nelson Bennett), and extended it to Burlington where it met the Seattle & Montana.

The Lehigh and Hudson River Railway (L&HR) was the smallest of the six railroads that were merged into Conrail in 1976.

The Northern Pacific Railway (reporting mark NP) was a transcontinental railroad that operated across the northern tier of the western United States, from Minnesota to the Pacific Northwest.

The Detroit, Grand Haven and Milwaukee Railway is a defunct railroad which operated in the US state of Michigan during the late 19th and early 20th centuries. Itself the product of several consolidations in the 1870s, it became part of the Grand Trunk Western Railroad in 1928.
