Need to add a tag that is appropriate for a help point -- an intercom facility (that I've never seen anybody actually use) that exists on many London stations, especially if the station is open when unattended.
- Can you give us any example picture of that? I currently do not understand exactly what you mean. Do you mean a kind of emergency phone? Or a remote ticket shop (via video chat) like http://www.merkur.de/bilder/2016/04/13/6306453/1983741020-kundin-videowand-4lLCVom5NG.jpg? --rurseekatze (talk) 22:16, 19 May 2016 (UTC)
- Here is an example  They are for general enquiries and to request assistance rather than specifically for emergency use. They definitely don't sell anything.
- As this concerns not just railways, but all forms of public transport, I suggest you to ask for that on the wiki discussion pages of public transport topics or any public transport mailing list. Also OpenRailwayMap focusses on infrastructure for railway operation, less on the passengers view. --rurseekatze (talk) 22:48, 19 May 2016 (UTC)
Also need a tag that is appropriate for oyster (prepaid) and contactless (pay as you go) card readers which can either be part of a walk-through ticket gate or a free standing reader on or near platform entrances. Hint: Those not familiar with London's ticketing might want to look at 
I suggest barrier=ticket_gate for the walk-through ticket reader but I'm less keen to suggest amenity=card_reader. They don't really provide either comfort, convenience or pleasure (dictionary definition of amenity). Facility=card_reader would make more sense, but we don't currently have a facility tag. --Harg (talk) 22:41, 19 May 2016 (UTC)
