The base order of r211As will most likely displace all the r46's off the A/C. That's is probably one of the reasons why the 8 car r179's are being retrofitted with CBTC, even though the J/Z is not getting CBTC any time.
The first option order will most likely make the C and G 100% full length and make the B/D 100% NTTs. The G will either get r179's from the C or get r160's from ENY. If CI gets r211As is going to be for the B.
I do see second option order going to Jamaica, regardless if it's open gangway or not, while CI gets some of the r160's plus all the r68's.
The MTA needs to exercise the second option order not just for CBTC, but also for the second phase of SAS, which will require more trains for the Q.
Is it true that the MTA included the r268 in the same capital program as the r262's???
