FFP - UNDER RIVER RAIL OPERATIONS Flashcards
Tunnel is a general term, which describes a below grade passageway. There are numerous underground tunnels between transit stations throughout the NYC Transit System. The Transit Authority also refers to its 14 sets of under river crossings as tunnels. Most under river tunnels actually consist of two separate structures referred to as tubes. What is the incorrect point about these tunnels/tubes?
A) Tubes are cylindrical in shape and are constructed of brick, concrete or tubular cast-iron. Some cast-iron tubes are lined with concrete. Tube walls are between 2 and 2 1/2 feet thick.
B) Most tubes are between 14 and 19 feet wide, which is only large enough to contain 2 tracks.
C) The 3rd rail alternates sides as it goes through the tunnel/tube.
D) It would be unsafe to walk between the running rails of the track due to the drainage trough. Personnel and evacuating passengers should walk in the area outside the rails.
ANSWER: B) Most tubes are between 14 and 19 feet wide, which is only large enough to contain 2 tracks. (INCORRECT)
- Only large ebough to contain ONE (1) TRACK
