There is a possibility it is BNDEP as well, since it is
registered with SBS6174T, which belongs to BNDEP.
He said before in the afternoon in the Citaro thread that 6180A
was behind 1903P, which IIRC both peak and non-peak hours that slot
is a HG slot because both BN A/P duties are usually one after
another. The BN S shift is usually in between 2 HG Citaros.
