Question: What two cities are home to the port of entry situated at the north end of the Port Subdivision railroad line?

<P0-S0> The Port Subdivision is a railroad line owned by CSX Transportation in the U.S. state of New York. <P0-S1>  The line runs from Selkirk north to Albany along a former New York Central Railroad line. <P0-S2>  At its south end, the Port Subdivision junctions with the Castleton Subdivision and River Subdivision; its north end is at the Port of Albany, served by the Albany Port Railroad. <SEP> <P1-S0>  The line then runs single track until 00N0.7 "11th Avenue" where it turns into double track and also meets the aforementioned, Wye track. <P1-S1>  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. <P1-S2>  Few more miles southward, the next major location appears. <P1-S3>  Commonly trains will stop before Delmas Ave when Kayne Ave is at capacity and await dispatch permission before moving south. <P1-S4>  Moving south, the line hits Radnor Yard at 000192. <P1-S5>  The Memphis, Tennessee Ex-L&N Bruceton Subdivision meets with the Terminal. <P1-S6>  When trains use this crossover northbound, such as Memphis bound trains from the A-2 line, they refer to it as "Long Lead". <P1-S7>  The tracks to the old shed are covered and removed. <P1-S8>  The Bruceton Sub begins at Church Street at 00N0.0. <P1-S9>  At Oak Street, our main terminal line goes south two miles to 000189.0 known as Criaghead or Vine Hill. <P1-S10>  The Radnor Cutoff carries the L&N mainline classification of "0BA" but meets the main at the same milepost from the Terminal. <P1-S11>  Once they get clearance, speed is decreased to 15, and at 0BA188.1 the EDD (Defect Detector) sounds for departures and arrivals. <P1-S12>  The Union Station is not an active station, but a historic hotel. <P1-S13>  There is a single departure/arrival track that meets the #2 track along with a crossover from #1 to #2 track. <P1-S14>  And now, the Terminal splits into two parts. <SEP> <P2-S0> The Tampa Terminal Subdivision is a railroad line owned by CSX Transportation in the U.S. State of Florida. <P2-S1>  There are 3 sections to the Tampa Terminal Subdivision. <P2-S2>  The first section runs from Control Point (CP)-YN to Gary, Florida and is 4 mi in length. <P2-S3>  At its north end it continues south from the Yeoman Subdivision and at its south end the west main leads to the Clearwater Subdivision while the east main leads to the Hooker's Point Lead. <P2-S4>  The second section runs from Mango, Florida to Tampa, Florida and is 8.1 miles in length. <P2-S5>  At its north end it continues south from the Lakeland Subdivision and at its south end it continues south as the Port Tampa Spur. <P2-S6>  The third section runs from Control Point (CP)-YN to East Tampa, Florida and is 7.3 miles in length. <P2-S7>  At its north end it continues south from the Yeoman Subdivision and at its south end it continues south as the Palmetto Subdivision. <SEP> <P3-S0> The Port of Albany–Rensselaer, widely known as the Port of Albany, is a port of entry in the United States with facilities on both sides of the Hudson River in Albany and Rensselaer, New York. <P3-S1>  Private and public port facilities have existed in both cities since the 17th century, with an increase in shipping after the Albany Basin and Erie Canal were built with public funds in 1825.
