Pictures of measurement or postal cars coupled with passenger trains?

[Yavianice]

I've been looking for pictures of post or maintenance cars being coupled to ordinary passenger service, such as this one, which seems to show a blue train sleeper having a maya34 car in front of it.

a maya34 being connected to an express hamanasu (below on the page)

and this one of the maya34 inspection car being hauled with an Akatsuki service

Does anyone have more examples of such combinations? Did the Twilight Express or more modern sleepers ever run with a maintenance or postal car?
