Philadelphia and Columbia Railroad (P&CR) (1834) was one of the earliest commercial railroads in the United States, running 82 mi from Philadelphia to Columbia, Pennsylvania, it was built by the Pennsylvania Canal Commission in lieu of a canal from Columbia to Philadelphia; in 1857 it became part of the Pennsylvania Railroad, and its trackage lives on today operated by Norfolk-Southern.
 The Philadelphia and Columbia Railroad's western terminus was located near the former ferry site known as Wright's Ferry, in the town once of that name, but now Columbia in Lancaster County.
 There the P&CR met with the Pennsylvania Canal—navigations and improvements on the Susquehanna River east bank approximately 30 mi south of Harrisburg, Pennsylvania.
 Most of its right-of-way was obtained by the actions of the Pennsylvania Canal Commission which operated the railroad under the various enabling acts of the Pennsylvania legislature known as the Main Line of Public Works in support of a far sighted plan to link the whole state by canals.
 With an engineering study reporting back a finding that obtaining sufficient waters to flood the intended 80+ mile canal from Philadelphia to Columbia, the Canal Commission and legislature authorized the railway on the right of way intended for the canal.

The Six Mile Run Reservoir Site, part of the Delaware and Raritan Canal State Park, is located in Franklin Township, Somerset County, New Jersey, United States.
 It is adjacent to the Delaware and Raritan Canal.
 It covers 3037 acre .
 The reservoir plan was to flood the Six Mile Run watershed.
 The Six Mile Run is a tributary of the Millstone River that, with its tributaries (Cross Brook, Middlebush Brook, Nine Mile Run and Steep Hill Brook and several other unnamed ones), drains a large area in central Franklin Township, Somerset County, New Jersey and western portions of North Brunswick and South Brunswick Townships in Middlesex County, New Jersey.
 It derives its name, along with other streams (Mile Run, Three Mile Run, Nine Mile Run, and Ten Mile Run), from the distance early surveyors estimated it was from the point where the historic King's Highway (now Rt. 27) left the Raritan River at New Brunswick to the point the roadway crossed the stream.
 The estimates were not very accurate but the stream names have remained in use ever since.
