Today's NY Daily News has an article stating that the Sixth Avenue signal upgrade (including towers) will postpone improvements to Lexington Avenue signal upgrade. Andrew Albert is quoted as objecting, as the Lex handles far more passengers. The article (behind a paywall) is quite detailed. It seems that what they call F (really Sixth Avenue from Jay Street north) has the right rolling stock to match CBTC, but the Lex doesn't. Maybe I'm confused, so forum readers, please help. Thanks!
