It doesn't take a great deal of advanced intel to figure out that subway stations get crowded during the morning rush. Put together a crude explosive with common materials, drop it off at the station early in the morning with a timer, drop one off on the bus set to go off after the first couple go off (catches the people fleeing the subway station).

Look at what a couple of rednoecks in the backwoods like McVeigh and Nichols pulled off with a U-Haul truck, fertilizer and blasting caps.
