Deregister some of 178 only for the time being. Only cameo CACs
2 replace deregistered ones lik: TIB773K, TIB781L,
TIB797S and many. Most probably, may become perm
bus.
Some of them might be perm service 178 already, replacing the 3 lay
up Nissan UDs (TIB371L, TIB372J and TIB1254K). Need to check it
out.
