Another message a bit after all the people chat
If anyone of you all is suspicious, see Welfare Island for where I saw this
Pros:
De-interling at Queens Plaza ((E) and (R) get one less merge)
Cons:
Shorter, 8 car (480 feet) trains at 63rd Street line stations, leading to the (M) getting crowded
The obvious Delancy-Essex situation would would lead to more people transferring
The MTA should NOT terminate (M)s at 2nd Avenue, keep the southern terminus as is with the 63rd Street swap
