NYC Tour Guide Complete Practice Test 2025

The 1 subway line is recognized for its route that runs the length of Manhattan from north to south, specifically from the northern tip of the Bronx down to the southern part of Manhattan, terminating in South Ferry. This line provides a crucial service, connecting various key neighborhoods and landmarks along the west side of the city, making it particularly significant for residents and tourists traveling across the island.

The other subway lines mentioned each have their distinctive routes: the 2 and 4 lines do also serve Manhattan but take a different path; the 2 line runs from the Bronx through to Brooklyn, while the 4 line primarily travels from the Bronx through Manhattan but does not extend to the same southern endpoint as the 1 line. The A line, although it crosses from the northern end of Manhattan to the southern part, does not consistently align along the length of the island from north to south, as it has express service and branches that alter its path. Thus, the 1 subway line is distinctive for its straight and continuous north-south trajectory throughout Manhattan.
