The Uptown Hudson Tubes are a pair of tunnels that carry PATH trains between Manhattan, New York City, to the east and Jersey City, New Jersey, to the west.The tubes originate at a junction of two PATH lines on the New Jersey shore and cross eastward under the Hudson River.
The Downtown Hudson Tubes use a roughly east-southeast to west-northwest path under the Hudson River, connecting Manhattan in the east with Jersey City in the west. Each track is located in its own tube, [1] which enables better ventilation by the so-called piston effect. When a train passes through the tunnel it pushes out the air in front of ...

Although the three portals are side by side in New Jersey, the north tube portal is one block west of the other two tubes' portals in New York City. [8] The north tube's eastern portal is near Eleventh Avenue between 38th and 39th Streets, while the center and south tubes emerge side by side at Tenth Avenue between 38th and 39th Streets. [8]
Each tube has a 29.5-foot (9.0 m) diameter, and the two tubes run 15 feet (4.6 m) apart under the Hudson River. The exteriors of each tube are composed of a series of cast iron rings, each of which comprises 14 curved steel pieces that are each 6 feet (1.8 m) long. The steel rings are covered by a 19-inch-thick (48 cm) layer of concrete.
