A very impassioned topic, to be sure! I would like to perhaps consolodate the concerns and see if we can all agree on the following:
1) Amtrak should probably observe the 10-7 rule for all announcements. If a sleeper pax wants to get up by 6 AM to be ready for breakfast by 6:30, then I'm sure the SCA can take care of that.
2) Amtrak should probably update their equipment (yeah - $$$). Have a speaker system in the private rooms that allow for ALL announcements (even between 7 am and 10 pm) with the exception of emergencies to be turned off. A switch in the PA system used by the crew would determine whether the announcement was an emergency or not. Return to using channels in the rooms, like the airlines. Maybe not 10 different Muzak channels, as just about everyone has a walkman now, but channel 1 for Scanner, channel 2 for rails & trails, etc. All overridden by any PA announcment. Add a volume control. Maybe emergency announcements should be made to the hallway speakers at a loud volume, so that the volume control in the room had relevancy.
3) Amtrak employees shouldn't go rogue. Stick to the script. Though it may be cute to some folks and maybe even enticing and revenue enhancing, the ill-will towards those who reject the call should trump the former.
4) Passengers should never NEED earplugs. But when they are used, the PA system shouldn't be so obnoxious that the earplugs are rendered useless.
