Hydraulic slide: pump sound is not cylinder evidence
Fictional coach with hydraulic through-frame room HY-TRAIN. Supplied pump-sound and control records; no hydraulic system is operated.
Customer says: The pump runs but the room does not move. Should we order a cylinder?
Original evidence-selection case. No pressure readings, valve commands or applicable hydraulic service limits have been established.
