With all due respect to the late great Senator Moynihan, I haven't read any compelling reason to move Penn Station and Madison Square Garden one block west. A simple redesign in-situ would save billions and the Garden management has already agreed to spend the money on its own property. Why shoudl the taxpayers subsidize such a move just so another vertical mall can be added to the Herald Square area? At a time of fiscal austerity, we need to separate the nice-to-have form the must-have. Moynihan station is a nice-to-have, the Second Avenue subway is a must-have, since that system is already overcrowded and will only grow more so as the LIRR gets a connection to Grand Central in a few years. The west side will grow just fine if the number 7 line is extended too; we don't need another shopping mall.
