BBDEP has 32 CDGEs, and ARBP has 17 CDGEs, which make a total of
49 CDGEs. Of these, 7 have the Voith gearbox.
Only 33 of these CDGEs are deployed, slightly more than 2/3 of
the CDGEs.
BBDEP has 16 spare WAB DDs, and 168 deployed WAB DDs. This is
lower than the 1:10 ratio of spare to total number of DDs.
In addition, all non-WAB DDs in BBDEP/ARBP are deployed.
So, expect frequent cameo downgrades in BBDEP.
BBDEP should be able to take more DDs once TT takes over the 4
bus services, but all 4 of them are in the last tranche of TT
takeover.
