One of the ones I really miss is H-O on the WCML behind or infront of (if propelling) a loco at night, with the blue flashes off the pantograph lighting up everything outside. You get it best when speed picks up though, but can sitll see it by standing next to the open window, and get the scream of the traction motors aswell. You can still get this on 'one' loco hauled trains, but to get next to the loco you have to go First Class, in which case its odd to pay the extra then spend most of the journey standing up. One thing I like to do, is to stand with the window open as the world flies past at 100mph+, especially at night I think it is really nice, even peaceful and calming (actually, I often do it when I am having a bad journey, with delays etc, and hate similar journeys on coffin stock without opening windows), just the fresh air is nice. At least we still have the HSTs and 'one' loco hauled sets, as well as railtours to enjoy heads-out. Then again, I have managed it on an electrostar once, since when coupling two units, someone not only left the seconds mans side door open, but also left the window down (or someone else had opened it when I got to it), so since the train was very busy, even though it was a coaches on a Sunday, I spent most of the journey sitting on the seconds mans seat in the centre cab, and naturally had the guard or anyone come along, I would have been a normal passenger who thought this was an extra seat

. That was early on though, and these days they seem much better at remembering to shut and lock that door.
