Slippery rail

Index Slippery rail

Slippery rail or low railhead adhesion, is a condition of railways (railroads) where contamination of the railhead causes trains to experience less adhesion (grip). [1]

Hudson Line (Metro-North)

Metro-North Railroad's Hudson Line is a commuter rail line running north from New York City along the east shore of the Hudson River. Metro-North service ends at Poughkeepsie, with Amtrak's Empire Corridor trains continuing north to and beyond Albany. The line was originally the Hudson River Railroad (and the Spuyten Duyvil and Port Morris Railroad south of Spuyten Duyvil), and later part of the famous Water Level Route of the New York Central Railroad. The Croton–Harmon station divides the line into two distinct segments. South of there, the line is electrified with third rail, serving suburban stations located relatively close together. Most of the electrified zone has four tracks, usually two express and local tracks in each direction. For a few miles in the Bronx there are only two or three tracks. Local service is usually provided by electric trains, while diesel trains run express. North of Croton–Harmon, the line is not electrified and is mostly double-tracked (with a few triple track areas); the stations are also spaced further apart. Service between Croton–Harmon and Poughkeepsie is provided by diesel trains; these generally run express and skip most of the lower stations. From just north of Spuyten Duyvil to the end of the line, the Hudson Line is shared with Amtrak's Empire Corridor routes up the river.
