The rail network, connecting New York City to its suburbs, consists of the Long Island Rail Road, Metro-North Railroad, and New Jersey Transit. The combined systems converge at Grand Central Terminal and Pennsylvania Station and contain more than 250 stations and 20 rail lines. In Queens, the elevated AirTrain people mover system connects JFK International Airport to the New York City Subway and the Long Island Rail Road; a separate AirTrain system is planned alongside the Grand Central Parkway to connect LaGuardia Airport to these transit systems. For intercity rail, New York City is served by Amtrak, whose busiest station by a significant margin is Pennsylvania Station on the West Side of Manhattan, from which Amtrak provides connections to Boston, Philadelphia, and Washington, D.C. along the Northeast Corridor, as well as long-distance train service to other North American cities.

Extract the answer to the question from the following context. Question: what has alcohol that you normally use on the tips of your finger for color removal Context: In May 1985, Gorbachev delivered a speech in Leningrad advocating reforms and an anti-alcohol campaign to tackle widespread alcoholism. Prices on vodka, wine, and beer were raised in order to make these drinks more expensive and a disincentive to consumers, and the introduction of rationing. Unlike most forms of rationing intended to conserve scarce goods, this was done to restrict sales with the overt goal of curtailing drunkenness. Gorbachev's plan also included billboards promoting sobriety, increased penalties for public drunkenness, and to censor drinking scenes from old movies. Although this program was not a direct copycat of Tsar Nicholas II's outright prohibition during World War I, Gorbachev faced the same adverse economic reaction as did the last Tsar. The disincentivization of alcohol consumption was a serious blow to the state budget according to Alexander Yakovlev, who noted annual collections of alcohol taxes decreased by 100 billion rubles. Alcohol production migrated to the black market, or through moonshining as some made "bathtub vodka" with homegrown potatoes. Poorer, less educated Russians resorted to drinking unhealthy substitutes such as nail polish, rubbing alcohol or men's cologne, which only served to be an additional burden on Russia's healthcare sector due to the subsequent poisoning cases. The purpose of these reforms, however, was to prop up the existing centrally planned economy, unlike later reforms, which tended toward market socialism.
