It depends on what trains you are talking about, the R160 from CIY are taking a break because of how much mileage they have, which resulted the N, Q to have some R68A's back from the B. There is a rumor that the R160 might go on the B since it only runs on weekdays.
hmm that's interesting. Is that why there have been 46's on the F? I was talking about the R68s and R46s. The R68s went into the G, and some of those R46s are on the F. Correct me if I'm wrong. I figured the surplus of these trains came from the cuts since the W sometimes used 68's (?) and the V 46's(?).
The R68 that were on the G IIRC were either from the W or the B/D ( Not sure about that) The R46 that were on the V were sent to the A to replace the R44, the F got the R46 back because of extras that were from the G, (Mostly used for put ins) but as i stated, the R160's have wayyyyy to much mileadge on them, so its a possibility u see a R46 F or a R68A on the N and Q once in a while.
going back to the R46's on the F didn't the MTA take them off the F to prevent them from getting stuck
in the tunnels after the chrystler street tunnel
Yes, but things change over time.
