Brompton on Irish Rail InterCity trains

Luggage racks on Mark IV and 22000 class where you'd store large cases.

Never heard a fold up bike referred to as a Brompton before

Most famous folding bike in the world.

Generally the luggage area and book a seat that allows me to see the bike if an intercity journey. It will fit on the overhead storage shelf but it is too dangerous and should not be used in my opinion. When folded and on its side it is very unstable, rocks, tilts, spins etc plus it if comes off and hits oneone it will do serious damage. Might be an option is a padded bag if such a thing exists but its still heavy to be above head height.

Commuter routes - depends. If empty train and no luggae space on the carriage I slot it on the floor in the seat beside me and only if near the door so that should teh carriage fill up I can hop out and stand with it at the carriage doors out of the way. On the dart I always stand with it beside me or I stand over it so as to keep as much space free for others when its jammed.

Its always intersting to see peoples reaction when you fold it on a platform, lots are amazed if they haven't seen it before and its been the cause of few chats out of curiosity.

i wouldnt count iphone as a genericized trademark, if someone is talking about an iPhone they generally mean an iPhone

you might have had a point with 'iPod' as a term for mp3 players in general
