Not sure about Service 261, so I shan't comment.
However for Services 382 & 385, only the latter operated DDs.
And the DDs used was the MBO305s before being replaced by the VO
2-axles. What I understand is that, HGDEP never operated the LO
2-axles, at the point of time Service 385 had DDs, that is.
Cheers and warm regards
