From the NY Times:
Metropolitan Transportation Authority officials are envisioning a subway car of the future that offers New Yorkers an out, ending the era of the captive car population.
This month, in a 142-page document outlining needs for the next 20 years, the authority noted the benefits of articulated trains — similar to accordion-style buses — that have no doors between cars, allowing unrestricted flow throughout the length of the subway.
“This will both maximize carrying capacity,” the authority said, and allow passengers to “move to less-crowded areas of the train, balancing loading and unloading times at all doors.”
The inclusion of articulated train cars in the report, a mild surprise to some transit advocates, does not guarantee that the cars will reach the rails anytime soon, or even at all; it was not clear how the cost of the articulated cars compares with that of nonarticulated cars. But for the first time in the subway system’s modern history, the authority appears poised to seriously consider a model adopted in cities like Berlin, Paris and Toronto.
