we had to take the evening train once on a business trip...around the beginning of Sept a few years back
it did get dark outside sooner than we thought it would...so we didn't see as much
also, the train is coming from Southern Washington State so it was already filled with passengers...so we were not able to get seats together...until some people got off in Bellingham, WA (the half way point)...we usually book business class but on this train those were all booked
that's why...even though it's early...we now always take the morning train!
