Railroads of the Chartiers Valley
Chartiers Branch, PC&Y, P&LE, and POHC · September 2026
Two railroads used the Chartiers Creek corridor. The Chartiers Valley / Chartiers Branch is the Pennsylvania Railroad line from Carnegie (Mansfield) to Washington. The Pittsburgh, Chartiers & Youghiogheny (PC&Y) is a shorter industrial railroad from McKees Rocks toward Woodville, with a branch onto Neville Island. Today’s Pittsburgh & Ohio Central (POHC) is a short line assembled in 1996 from pieces of both.

The two Chartiers lines
| Chartiers Valley / PRR Chartiers Branch | Pittsburgh, Chartiers & Youghiogheny | |
|---|---|---|
| Purpose | Pittsburgh–Washington through the valley | McKees Rocks industrial line, Neville Island, and a connection into the PRR at Mansfield/Woodville |
| Incorporated | Chartiers Valley Railroad, 7 February 1853 | PC&Y, 26 October 1881 (from two 1880–81 companies) |
| Opened | Carnegie–Canonsburg 19 Dec 1870; to Washington 18 May 1871 | Built in the 1880s from McKees Rocks up the valley |
| Controlling roads | PRR / Panhandle (PC&StL, then PCC&StL) | Jointly owned 50/50 by P&LE and the PRR’s PCC&StL from 1892–93 |
| Later owners | Penn Central, Conrail, then the 1996 short-line sale | Operated under its own name into the Conrail era; 16 miles sold to PIR in 1996 |
| Today | South end of POHC, through Arden | Neville Island branch and McKees Rocks connections on POHC |
In 1907 the Chartiers Railway (the Washington line) was consolidated into the PCC&StL Panhandle. The PC&Y stayed a separate company, owned half by P&LE and half by PCC&StL, and ran with its own operating organization.
Chartiers Valley Railroad / PRR Chartiers Branch
A survey down Chartiers Creek toward Pittsburgh was made in 1831 (Washington & Pittsburgh Railroad charter; stock did not sell). Similar attempts failed in the 1830s–40s.
7 February 1853 — Chartiers Valley Railroad incorporated to build from Pittsburgh via Canonsburg to Washington. Grading started; by 1856–57 money ran out (Panic of 1857). The company was sold at foreclosure 30 October 1866. The Pennsylvania Railroad acquired the assets (Bridgeville Area Historical Society: about $45,100), mainly for the right-of-way from Mansfield into Pittsburgh.
4 June 1867 — Chartiers Railway Company organized. With PRR backing it finished the line. Regular service Carnegie (Mansfield)–Canonsburg 19 December 1870; Washington 18 May 1871. About 23 miles, Chartiers Creek crossed many times, two tunnels.
8 December 1871 — leased to the Pittsburgh, Cincinnati & St. Louis Railway (Panhandle) as the Chartiers Branch. PCC&StL acquired the company 20–21 November 1907.
The line was double-tracked Carnegie–Houston (about 15 miles) by 1904. Coal branches left at Bridgeville (Bridgeville & McDonald, 1890, toward Cecil/Bishop) and later to Westland, Palanka, and Manifold (1904). Connections included:
- PC&Y at Glenn and Woodville
- Montour Railroad at Hills (about MP 8.6)
- Pittsburgh & West Virginia (P&WV) near Bridgeville
- B&O at Washington, via the jointly owned Tylerdale Connecting, and the narrow-gauge Waynesburg & Washington
Nine daily Pittsburgh–Washington passenger round trips in 1926. Last scheduled passenger train July 1952. Reduced to single track by 1951. Most mine branches gone by 1972. Conrail abandoned Tylerdale–Washington (1.8 miles) in 1982 and Tylerdale–near Arden (1.4 miles) in 1984. The remaining Chartiers industrial track was sold in 1996. The Pennsylvania Trolley Museum’s standard-gauge neighbor at Washington is this line.
Stations along the valley (Chartiers Branch employee lists and valuation maps): Glenn, Woodville, Bower Hill, Kirwan, Bridgeville, Mayview, Boyce, Hills, Canonsburg, Houston, Arden, Washington. Several stations still stand (Bridgeville passenger; the old freight station is built into Silhol’s warehouse; Boyce; Canonsburg; Washington freight and passenger).
Pittsburgh, Chartiers & Youghiogheny Railway
Promoters in 1880–81 planned a railroad from McKees Rocks up the Chartiers Valley, then east toward Library, Elizabeth, and eventually Latrobe. They chartered the Chartiers and Mansfield Valley Railway (15 December 1880) and McLaughlin’s and Saw Mill Run Railway (9 May 1881), then consolidated them as the Pittsburgh, Chartiers & Youghiogheny Railway on 26 October 1881.
What was built was more modest: McKees Rocks up the valley to Mansfield (Carnegie), shared right-of-way toward Woodville, then branches (Beechmont, Beadling). The Beadling branch was taken up for scrap during World War II. The Youghiogheny end of the corporate name remained a plan.
26 May 1892 — P&LE bought a half interest. PCC&StL held the other half. A contract provided for operation of the road. ICC valuation: each owner 50 percent of capital stock; PC&Y kept its own operating organization. Bridgeville local history often dates the joint acquisition “by 1893.”
The PC&Y is the railroad that reached Neville Island (Fleming Park bridge over the back channel) and interchanged with American Steel & Wire’s Pittsburgh & Ohio Valley Railway on the island.
P&LE was a New York Central property (NYC interest from 1879, control by the 1880s).
Baltimore & Ohio in this neighborhood
B&O’s own Pittsburgh freight geography sat on other routes: the Pittsburgh Division toward Cumberland and Baltimore, and the former Pittsburgh & Western on the north side of the Ohio. At Washington, B&O met the Chartiers Branch through the jointly owned Tylerdale Connecting Railroad.
In 1934 B&O obtained trackage rights over the P&LE between McKeesport and New Castle, used by passenger trains such as the Capitol Limited. B&O also held a one-third interest in the Monongahela Railway, the coal road south of the Monongahela. The CSX main through McKees Rocks and onto Neville Island is the former P&LE.
Pittsburgh & Ohio Valley Railway (island industrial)
Incorporated 5 December 1899, owned by American Steel & Wire. Built February 1900–October 1902 on AS&W land on Neville Island. Interchanged with the PC&Y. Commandeered by the Ordnance Department 20 September 1918–1 July 1919. A 1923 Pittsburgh Plan note lists about 2.04 miles, U.S. Steel–owned, also connecting toward the P&LE. This is the island switching railroad.
Short-line era: PIR, then POHC
6 December 1996 (STB notices) — Pittsburgh Industrial Railroad (PIR), a RailTex company, acquired:
- about 32.7 miles from Conrail (Chartiers industrial track, including Carnegie–South Strabane / Arden)
- about 16.0 miles from PC&Y (including McKees Rocks–Neville Island)
- incidental CSX trackage rights on Neville Island to connect those pieces
RailAmerica bought RailTex in February 2000 and sold PIR in December 2000. Ohio Central renamed it Pittsburgh & Ohio Central Railroad (POHC, also styled P&OHC). Genesee & Wyoming announced purchase of the Ohio Central system on 4 August 2008; STB approved 30 December 2008. POHC continues as a G&W short line: office at McKees Rocks, track from Neville Island south toward Arden. Commodities include chemicals, plastics, metals, minerals, and petroleum products.
Typical jobs: interchange with NS at Duff Junction, Neville Island work, and a south turn toward Carnegie or Arden.
Junctions and yards: Duff and POV
Duff Junction and POV Junction are connections. Cars are handed off at the junction. The yards that build and break those cuts sit next door.
Duff Junction (POHC ↔ Norfolk Southern)
USGS maps label the spot Duffs–Scully Junction. It sits in the Crafton / Thornburg / Scott Township area, where the Chartiers / PC&Y track meets the former PRR Panhandle. G&W lists the NS interchange as Duffs Junction.
There is no separate “Duff Yard.” The yard on that ground is Scully Yard, a former PRR Panhandle facility (roundhouse and engine terminal in the steam era). POHC crews start at McKees Rocks, run to Duff Junction, interchange with the NS local there, and sort at the junction and at Scully. Maps still show Scully as active POHC track, with fewer leads than the old Panhandle yard.
NS’s heavy Pittsburgh classification is elsewhere on the NS system (Conway and other mains). What meets POHC at Duff is the NS local that works this Panhandle connection.
POV Junction (POHC ↔ CSX)
G&W lists the CSX interchange as Pov Junction, Pa. On the CSX Pittsburgh Subdivision that is Neville interlocking, about milepost PLE 5.7, where POHC joins CSX to cross the shared back-channel bridge onto the island. (POHC also crosses the CSX main near McKees Rocks at about PLE 3.75.)
The former P&LE McKees Rocks Yard at the mainland end of that scene is largely gone. What remains:
- CSX works the island with local D749, based at Demmler Yard (about PLY 13, McKeesport). D749 uses the east end of Neville Island; photographs show a small CSX yard on the island itself.
- POHC works the west / north end of the island from its McKees Rocks office, under CSX dispatcher authority across the bridge. A small POHC yard sat on the north end of the island, visible from Neville Road.
So: POV Junction is the bridge connection. CSX classifies at Demmler and spots on the island’s east-end tracks. POHC classifies at McKees Rocks / Scully and spots on the island’s west-end tracks.
McKees Rocks and PAM
POHC’s office and power sit at McKees Rocks. CSX (former P&LE) still runs the Ohio River main here, west toward Aliquippa, New Castle, and Chicago.
The Pittsburgh, Allegheny & McKees Rocks Railroad (PAM) is the switching road inside the Pressed Steel / industrial complex. Parent real estate later sat with McKees Rocks Industrial Enterprises (MRIE); PAM kept the track. A 2023 STB notice records a sale of about 3.36 miles to McKees Rocks Railroad LLC. Pressed Steel Car’s sternwheel Steel Queen (built 1901) towed and ferried on the Ohio here until she burned at Woods Run on 16 October 1926.
Other connecting railroads
Carnegie / Rook. The Pittsburgh & West Virginia (Wabash Pittsburgh Terminal, reorganized 1917 as P&WV) built through the south hills; Rook Yard is its Carnegie-area yard. P&WV went to the Nickel Plate, then N&W (1964), later today’s Wheeling & Lake Erie. West toward Mingo Junction / Brewster is W&LE geography. The Montour Railroad (P&LE coal belt) connected with the Chartiers Branch at Hills.
Port Perry Branch. Norfolk Southern’s (ex-PRR) high-clearance bypass around downtown Pittsburgh: Pittsburgh Line at North Versailles, Port Perry Tunnel, Port Perry Bridge over the Monongahela, connection to the Mon Line at Duquesne. CSX’s Pittsburgh Sub crosses that branch near PLY 11. It is the stack-train cut-across, a different piece of NS from the Panhandle connection at Duff.
