i think this happened..
2 striders from 93 went 91, 91 VOs go spare
2 citaros from 5 went 93, 2 scania/DD replaced them.
more verification needed.
6051 on 93 today with 93 guides in the bus. prob 6050 also went
to 93.
1945 1962 2639 likely out, 6193 6214 6141 might be replacing them
6193 replacement looks like a mark iv b10m either 2596 2676 2732
but for 2639 i suspect swop with 6141 which is bb 175.
