Question: The lad of Union Station in New Jersey remains the property of a Class I railroad that operates how many route miles?
Context: The Norfolk Southern Railway (reporting mark NS) is a Class I railroad in the United States.  With headquarters in Norfolk, Virginia, the company operates 36,200 route miles in 22 eastern states, the District of Columbia, and has rights in Canada from Buffalo to Toronto and over the Albany to Montreal route.  NS is responsible for maintaining 29,000 miles, with the remainder being operated under trackage rights from other parties responsible for maintenance.  The common commodity hauled on the railroad is coal from mines in Indiana, Kentucky, Pennsylvania, Tennessee, Virginia, and West Virginia.  The railroad also offers the largest intermodal network in eastern North America. Phillipsburg Union Station is an inactive railroad station in Phillipsburg, New Jersey, United States at 178 South Main Street.  Opened in 1914, Union Station was built by the Delaware, Lackawanna & Western Railroad (DL&W) and shared with the Central Railroad of New Jersey (CNJ) and was situated where the lines merged before the bridge crossing the Delaware River.  Designed by Frank J. Nies, the architect who produced many of DL&W stations now listed state and federal registers of historic places, the 2 1/2 story, 3 bay brick building is unusual example of a union station and a representation of early 20th century Prairie style architecture.  The Phillipsburg Union Signal Tower, or PU Tower, is nearby. Sydenham (London) is a railway station in Sydenham in the London Borough of Lewisham, South London.  Originally opened in 1839, the station is located on the former Croydon Canal, which is now a branch of the Brighton Main Line, often known as the Sydenham Corridor.  Sydenham falls within Travelcard Zone 3 and is served by London Overground and Southern.  The station is 6 route miles (9.6 km) from , 9.7 route miles (15.6 km) from and 10.5 route miles (16.8 km) from . Union Station is a New Jersey Transit railroad station in Union County, New Jersey.  Located on the Conrail Lehigh Line, Union is served by Raritan Valley Line trains that travel between Newark Penn Station and Raritan.  There is also limited service to and from High Bridge and New York Penn Station and one morning train to Hoboken Terminal.  The physical structures of the station are owned by New Jersey Transit, however the land remains property of Norfolk Southern Railway, in accordance with the 1999 buyout of Consolidated Rail Corporation by Norfolk Southern Railway and CSX Corporation. Amtrak's 25 Hz traction power system is a traction power grid operated by Amtrak along the southern portion of its Northeast Corridor (NEC): the 225 route miles (362 km) between Washington, D.C. and New York City and the 104 route miles (167 km) between Philadelphia and Harrisburg, Pennsylvania.  The Pennsylvania Railroad constructed it between 1915 and 1938.  Amtrak inherited the system from Penn Central, the successor to Pennsylvania Railroad, in 1976 along with the Northeast Corridor.  This is the reason for using 25 Hz, as opposed to 60 Hz – which is the standard for power transmission in North America.  In addition to serving the NEC, the system provides power to New Jersey Transit Rail Operations (NJT), the Southeastern Pennsylvania Transportation Authority (SEPTA) and the Maryland Area Regional Commuter Train (MARC).  Only about half of the system's electrical capacity is used by Amtrak.  The remainder is sold to the commuter railroads who operate their trains along the corridor. The Kansas City Southern Railway Company (reporting mark KCS) , owned by Kansas City Southern, is the smallest and third-oldest Class I railroad in North America (just behind Union Pacific Railroad and Canadian Pacific Railway) still in operation.  Founded in 1887, KCS currently operates in 10 central U.S. states.  KCS also owns and indirectly operates Kansas City Southern de México (KCSM) in the central and northeastern states of Mexico, and is the only Class I Railroad to own any track both inside and outside of Mexico's boundaries (Ferromex is the only other Class I operating in Mexico).  KCS owns about 9,600 kilometers (6,000 route miles) of track, including trackage owned by subsidiaries. The First Street Tunnel is a two-track, soft-earth tunnel built between 1904 and 1906 by the Washington Terminal Company to serve as the southern approach to Union Station in Washington, D.C. Currently owned by Amtrak, it connects to lower-level tracks and platforms at the station, passes under Capitol Hill and connects to the RF&P Subdivision (CSX Transportation) and Long Bridge, offering through railway service to Alexandria, Virginia, and points west and south.  Unlike the Northeast Corridor tracks north of Union Station, the tunnel tracks are not electrified, so southbound trains leaving Union Station must switch to diesel locomotives before entering the tunnel.  Exiting Union Station, the tunnel runs due south under First Street NE and SE before curving to the southwest under a parking lot near the Capitol South Metro station.  Its southern portal is just east of South Capitol Street at the intersection of D Street SE and New Jersey Avenue SE. Union Station is a former train station in Seattle, Washington, United States, constructed between 1910 and 1911 to serve the Union Pacific Railroad and the Milwaukee Road.  It was originally named Oregon and Washington Station, after a subsidiary line of the Union Pacific.  Located at the corner of S. Jackson Street and 4th Avenue S. in the Pioneer Square neighborhood, the station opened on May 20, 1911.  The Milwaukee Road discontinued passenger service to Union Station 50 years later, on May 22, 1961, and the Union Pacific followed suit on April 30, 1971.  With no passenger rail service serving Seattle from Union Station, the building remained largely empty.  After nearly 30 years of sitting idle, the station finally experienced an expansive renovation supported by Nitze-Stagen with financial backing from Paul Allen.  The Union Station renovation was the winner of the 2000 National Historic Preservation Award.  It now serves as the headquarters of Sound Transit; its grand hall is rented out to the public for weddings and other events. Union Station, also known as New Haven Railroad Station (IATA: ZVE) or simply New Haven, is the main railroad passenger station in New Haven, Connecticut.  Designed by noted American architect Cass Gilbert, the beaux-arts Union Station was completed and opened in 1920 after the previous Union Station (which was located at the foot of Meadow Street, near the site of the current Union Station parking garage) was destroyed by fire.  It served the New York, New Haven and Hartford Railroad until it fell into decline, along with the rest of the railroad industry in North America after World War II.  It was shuttered in 1972, leaving only the under-track 'subway' open for passengers, and listed on the National Register of Historic Places on September 3, 1975, but it was almost demolished before the Northeast Corridor Improvement Project came to the rescue in 1979.  Reopened after extensive renovations in early 1985, it is now the premier gateway to the city. The Nashville Terminal Subdivision is a railroad line owned by CSX Transportation in the U.S. State of Tennessee.  The Subdivision is broken up into 5 sections all in Nashville, Tennessee.  The northern part of the Terminal is in Madison, Tennessee at milepost 000/0BA 174 on the southern end of the Ex-L&N Mainline Subdivision at Monfort.  Disptach for the Mainline Sub is known as "LD" which is part of the Cincinnati Division.  From here in Madison begins the double track that stays for another 22 miles south to Brentwood, Tennessee.  At milepost 000/0BA/00H 176.6, the famous Johnny Cash "Amqui" location where the Ex-L&N Evansville, Indiana line, the Henderson Subdivision meets with the Terminal.  Dispatch for the Henderson Sub is known as "SA" and operates on AAR58.  There are two crossings near each other, Williams Ave and Nesbitt Lane at Amqui.  From here the Terminal goes south about 2 miles to the Nashville National Cemetery to the first major location, known as Ekin, 000179, where there is a cross over track from number 1 to number 2 track (left to right track).  There is also the first EDD (Defect Detector) at 000179.1.  Few more miles southward, the next major location appears.  At 000181.0, Maplewood is a major location for the Terminal.  From here the regular Terminal goes south to swap crews at Kayne Ave, and the right side, Radnor Cutoff, detours the city and gives yard departures and arrivals direct access to and from Radnor yard to cities like Louisville and Chicago.  The Cutoff runs from Maplewood to Shelby Park double track.  From Shebly the track converges into one to pass the historic Shelby bridge, then it opens back to double track.  From there, the cutoff hits the Intermediates at 0BA187.0 known as Chicken Pike.  The Radnor Cutoff carries the L&N mainline classification of "0BA" but meets the main at the same milepost from the Terminal.  At Chicken Pike, trains are staged to await arrival to Radnor yard.  Once they get clearance, speed is decreased to 15, and at 0BA188.1 the EDD (Defect Detector) sounds for departures and arrivals.  This location is known as North Radnor.  The right track diverging from the #2 is known as A-1, it is for departure trains to Chattanooga and Atlanta.  The left track which goes west from the #1 is known as A-2, and serves as a departure track to Memphis, and if the cutoff is out of service, all northbound departures.  The interesting piece of Maplewood is the crossovers that are there to move trains from the Cutoff to the Main.  Both lines remain double track for a while.  The main runs south for 2 more miles until the Intermediate signals at 000183.0.  Commonly trains will stop before Delmas Ave when Kayne Ave is at capacity and await dispatch permission before moving south.  From here, the main continues south until the CR Cumberland River Swingbridge, where the main converges into a single track shortly to cross the bridge.  At this point, trains had been running at track speed of around 40.  From the drawbridge into town, speed is reduced to around 10.  After the bridge is passed, the main returns to double track in downtown.  On the #1 track about a half a mile south, another connecting track is present.  This is the Wye track that connects the main with the Bruceton side, while rarely used for mainline trains, locals and river jobs use it.  The location is known as 8th Avenue or 8th Avenue Wye.  The main then runs down to Kayne Ave, the central hotbed of all Nashville thru traffic.  The Memphis, Tennessee Ex-L&N Bruceton Subdivision meets with the Terminal.  The Bruceton Sub begins at Church Street at 00N0.0.  The line then runs single track until 00N0.7 "11th Avenue" where it turns into double track and also meets the aforementioned, Wye track.  The Bruceton line then goes southwest a while to the next signals, at "Shops".  Now speed has been increased.  The line is still double track until "Sellars", where speed is increased to 40 and jurisdiction transferred to the SD Dispatcher.  For a short time, 4 main tracks are present and an additional fifth track for switchers and yard movements.  The tracks from left to right in Kayne Ave are as follows: 100, 99, 98, 12, 3.  The Kayne Ave yard is also here in this area, which houses some frieght and some switcher engines.  The tracks to the old shed are covered and removed.  The Union Station is not an active station, but a historic hotel.  Crew change usually occurs at the "walkway" which is under the Demombreun St bridge by the Kayne Ave Tower.  This is also where the Ex-NC&StL Chattanooga Subdivision begins.  Then tracks run south to Fogg St/South End where things get complicated.  At milepost 000/0BA/00J187 the 98 track merges into the 12 track, making for 3 tracks now.  There is a crossover from 99 to 12, also a crossover from 12 to 3.  About 2/10ths of a mile down the 99 merges into the 12 track reducing the tracks back to the regular double.  About 4/10ths of a mile down the line from Fogg St, 000187.4, Oak St, is a crossover track from #2 to #1 (the track names are no longer 3 and 12, but are back to regular names).  When trains use this crossover northbound, such as Memphis bound trains from the A-2 line, they refer to it as "Long Lead".  And now, the Terminal splits into two parts.  The right side turns into a single track shortly, and will become the Chattanooga Subdivision, and the left side runs south to Brentwood.  The right track runs single shortly until double track for a while.  This begins part of the Chattanooga Sub or J-Line.  The #2 meets with the A-2 connection track at 00J2.2 known as A-2.  Speed is now increased to 40.  Commonly northbounds will stage at 4th Ave on the #1 to await clearance.  Now about a mile down the #1 meets the A-1 connection line.  At 00J3.6 known as A-1.  Further down the double track ends at Glencliff (00J4.9).  Now it runs single for three miles until it hits Danley, which has the D Line connection track, which is an arrival track for incoming Radnor trains from the J Line.  At Danley, the Terminal ends but the same dispatcher handles traffic, "SC".  At Oak Street, our main terminal line goes south two miles to 000189.0 known as Criaghead or Vine Hill.  There is a crossover here from #1 to #2 track.  And there is also a connection/delivery track to the Nashville and Eastern Railroad which connects the Tennessee Central Railroad Museum to a major railroad.  Trains sometimes stop on the #2 before Craighead if they are waiting to enter Radnor yard.  Sometimes trains wait on the #1 at the Berry Road crossing if they await arrival to Kayne Ave. At this point, speed has been increased to 30 from 10.  Moving south, the line hits Radnor Yard at 000192.  The #2 track meets the E-Line arrival track which most Memphis trains and locals use.  The B-Line which meets the #1 track is used for departures out of the C yard and local jobs.  At Mayton, 000192.3, the B line meets the #1 track, and there is a crossover track from #2 to #1.  Speed is now at 40.  2 miles south, at 000194.0, South Radnor, the next intersection is present.  This is where the Radnor A yard meets the main.  There is a single departure/arrival track that meets the #2 track along with a crossover from #1 to #2 track.  Commonly, the #2 track south of the signals is used to halt trains.  This location is known as TVA, because of the power station that is adjacent.  From here the Terminal runs about 2.5 miles south until we hit the southern tip.  The tracks converge onto one single main, at 000/0BA196.6 known as Brentwood.  Speed is increased to 50 and jurisdiction to the S.E. dispatcher.  The right track is the main, S&NA North, while the left track is the Nashville Subdivision which runs to Columbia and exchanges freight with the TSRR.  The Nashville Terminal Subdivision is one of the busiest locations on the CSX network, and one of the most important.
