Here is the finished RUSH HOUR PROJECT for subway expansion.
Purposes of lines:
10/Amsterdam Ave: Lines will supplement 8th Ave & B'way line services, mainly between 57 Street & 191 Street, due to Super Express service between 59 Street & 125 Street on & and overcrowding on (1)/(2)/(3). (Cars: R40 Slant & M, R44, R46, R160, R211.)
5 Avenue: Lines will supplement East Side services. (Cars: R62, R62A, R33A & R36 (Redbirds) before 2003, R142, R177.)
: Direct service to Battery Park City from Brooklyn. (Cars: R46, R211)
(V)/(U) & (Y): To alleviate crowding on (J)/(Z) line & better service Woodhaven, Ozone Park, Lindenwood & Howard Beach.
New Yard at Decatur St for Y train. (Decatur St Yard)

The only diference is that the lines go up Amsterdam Ave between 57 Street & 110 Street.
