Packed trains has been a problem on the for quite some time, you’ll see people waiting for another train at 74th Street because the trains are fully packed, 11 Car set R188’s doesn’t solve the problem at all, unless the MTA had the idea of building a new northern Blvd subway line, to ease crowds on the , majority of subway lines have this problem, and they don’t have an extra pair set, the idea of the 11 Car set was for the worlds fair only, I could be wrong tho
