Bright lighting is one of the worst things about train travel at night, it makes it so hard to relax, or just to look out of the window (since all you can see is the reflection of inside the carriage). Add to this hard seats and coldness (due to the HVAC being set to low), loud announcements (epecially automatic ones), and constant beeps etc, and it really spoils night travelling on trains. Actually, it's one thing where coaches really win, I find they have a much nicer ambience for night travelling, with dimmed lights, warmth, and modern coaches are often quieter and smoother than trains. Seats often arn't much better though, if not worse, but then get the atmosphere right and relaxing is easy anywhere. At least on HSTs, there is the option of the droplights in the vestibules for viewing outside (the world at night can be very pleasent when viewed from a train, especially around christmas when places are lit up). Of cource, HSTs arn't quite up to electrics, with the regular blue flashes from the overhead/third rail.
