42nd Street Light Rail?

"Advocates of light rail, which would stop at every intersection along 42nd Street, said that there was still a need for better surface transportation, since the No. 7 line has no stops east of Grand Central Terminal at Lexington Avenue."

"An economic study commissioned by Vision 42 with grant money and done by the consulting firm Urbanomics of New York, projected that about 398 office properties along 42nd Street would have an average increase in lot value of $188 a square foot because of the time saved with a light rail line, a combined increase in value of 4 percent. Jeffrey Gural, the chairman of Newmark Knight Frank, a real estate company that manages office buildings along 42nd Street, said it would make sense to connect the Javits Center to the United Nations, which currently has no subway stop."
