Question came up the other day ... "have
GWR▸ printed their latest cycling leaflet" and the person who asked said (I think) that he mad managed to find one of 2016. I have picked up one today dated August 2018 which does include
IET▸ information, etc ... 12 sided of data (or 2 covers and 10 sides) -
https://www.gwr.com/plan-journey/journey-information/on-board/cycles also contains current (?) data, and there's a short url for that -
