Add on:
SBS 1933C
(HGDEP SP HGDEP 119)
SBS 1997T
(HGDEP SP HGDEP 156) Add P shift (thanks service_238
I almost forgot 
)
All former 578 crossovers have been removed and all 4 578 buses
do 159A now before going back to 578. As such the former crossover
services 80, 119 & 156 each received fleet addition (156 add P
shift while the other 2 add S shift). 372 remains unchanged as it
seems.
After the fleet addition into 119 the maximum frequency actually
increased from 18 mins around noontime previously to
24 mins and from 19 mins in the late night to
25 mins. 
/GG =)

frame:
