Narrative:

Fpf release #1 as well as fpf release #2 show us filed via the TRALR2 departure dvc transition. We obtained the pre departure clearance for flight. The 'filed route' section of the pre departure clearance also showed the TRALR2 departure. 'Revised segment' section of the pre departure clearance said none. The 'remarks' section of the pre departure clearance only said 'comply with altitudes on SID. Departure control frequency 133.95.' that is the information we departed with. On climb out when we switched to departure control frequency; the controller asked us which departure we were on. We said the tralr departure. He said we were supposed to be on the staav departure. We told him that was not what our pre departure clearance said. He then came back and told us to copy a phone number to call about a possible violation. En route; we reviewed all of the information we had. Nothing showed that we were supposed to do the staav departure. We sent an ACARS to the dispatcher to advise him what had happened; and told him we would file a report. On the ground at destination; we talked to the assistant chief pilot about what had happened; and showed him the paperwork and pre departure clearance we had. He agreed with us. The captain called the number ATC had asked us to call. When ATC said they wanted to see a copy of the pre departure clearance; the assistant chief pilot faxed it to them. The person the captain talked to on the phone in las said that the tralr departure was not used for runway 25 departures; but our company kept filing it anyway. Even so; our pre departure clearance did not give any change to what had been filed -- it assigned the TRALR2 departure. If that changed after we had called up and printed the pre departure clearance; neither las clearance; ground control; tower; or departure control informed us of any change to our pre departure clearance clearance. We flew the departure that we had filed; and that the pre departure clearance had instructed us to do -- as we are supposed to do. Supplemental information from acn 733379: the captain notified me via ACARS that las departure told him that he should be on the STAAV3 departure and they wanted him to call when he got on the ground. The captain said that release #1 and #2 as well as the pre departure clearance showed the TRALR2 departure. I verified that I had filed the flight on the TRALR2 departure. The pre departure clearance in computer show the STAAV3 departure as a revised segment. The captain said that the pre departure clearance (that he still had a copy of) did not have any revised segments. Callback conversation with reporter acn 733647 revealed the following information: the captain reiterated receipt of a pre departure clearance with the tralr SID. Reporter advised the dispatcher had received a copy of a revised SID which showed the staav.
