IMHO here's what I think should happen when the R179s come in at ENY and 207 st yard
R179, R46, (with an occasional R32)
R68A, R46
all R160, a few R32s
R68 with some R68A
all R160 (would say R32s but the riders would most likely complain)
R160 with some R32s
all R46s
(J)/(Z) all R160 with some R179 and R143s
R143, R160
all R160
R160s, a few R68As
(Q)R179,R160,some R68s
®R46,R160
(W)R160, R32s
The will have R179s so IMO they should push those R46s to coney island yard for the and this is my theory don't take it to seriously
