Hugh Pickens DOT Com writes "Many of New York City's subway cars are well past their prime and due for fleet replacement, most strikingly those on the C line, known by their model number, R32, and for the tin-can siding that will continue rolling beneath Eighth Avenue for at least a few more years. Now the NYT reports that transit planners have urged the Metropolitan Transportation Authority to consider articulated subway cars for any future fleet upgrades. Articulated cars, already adopted in cities like Berlin, Paris, and Toronto, have no doors between cars, allowing unrestricted flow throughout the length of the train that could increase capacity by 8 percent to 10 percent. Adam Lisberg, the authority's chief spokesman, says that increased capacity could also improve 'dwell time' — the period during which a train is stopped in a station, often because of overcrowding — and allow more trains to run. 'We're one of the largest systems in the world that doesn't do it,' says Richard Barone, the director of transportation programs at the Regional Plan Association. 'Our trains don't function right now to allow people to circulate.' Articulation also has the benefit of making empty trains feel safer. By allowing passengers the ability to move between cars easily and to see passengers throughout the train, the isolation that can sometimes feel dangerous on a late-night subway is less of an issue, simply because the whole train is joined together like one huge car. But not everyone embraces the idea. Elizabeth Kubany who works in the Flatiron district, expressed a fondness for the current configuration, suggesting that the separated cars were more 'intimate' binding passenger to passenger in an increasingly antisocial age. Then she reconsidered. 'You don't really want to be intimate with people on the train.'"
