Three years ago, I posted on my proposal of the IRT Flushing Line for TSW can see it here: https://forums.dovetailgames.com/threads/irt-flushing-line.18449/#post-398276. The only line goes over ten cars (11) & between Manhattan/Queens. That & L lines goes under 45 minutes & 25 stations: L got 24 (most of them we're underground northwest of Broadway Jct) & 7 got 22 (most of them we're elevated between Court Sq & Mets), with R188 fleet (formerly on the 6 line with R142A's 7221-7590). With rush-hour express to Manhattan in the morning, PM to Queens & some local trains terminated/started @ Mets or 111th St (Roosevelt). The Corona Yard is located south of Mets-Willets Point station.
