I have been traveling by train for several years but do not yet have a good sense of what fair sleeper car attendent tips are. My most frequent trips are overnights from Spokane that leave at 2:15 and 2:45 a.m. and arrive in Seattle or Portland about 10:00 a.m. with return legs leaving about 4:45 p.m. returning after midnight. On these trips the attendent's service that I utilize is often limited to putting the bed down and back up. Next month I will travel again on the Empire Builder Eastbond which is about a 35 hour trip on a single train. A comparable travel time train that I take is Portland to L.A. on the Coast Starlight. My tipping to date has generally been $10 to $20 flat (never $10 on the long trips). I am interested in comments on what prevailing tip ranges are for 8 hour overnights and for longer trips like trains like 7 & 8 and 11 & 14.
