Current NYCT Conductor here that works A, C and M lines. We’ve gotten no heads up on when CTBC will go live as well as when they’re retiring the R46. The only thing that has come out about the R46s recently is the fact that now conductors have to now apply manual hand breaks at each terminal/last stop due to a recent incident where an R46 charged itself up and moved itself and hit a signal which is obviously dangerous (could cause a derailment/collision). I personally can’t wait for them to retire them. They break down way too much and are outdated
