I have a collection of pre-1994 British Rail leaflets, timetables (including a 1984 Leicester-London timetable) and other literature, including a few InterCity magazines, First Class Pullman brochures and InterCity Shuttle leaflets, and various First Class onboard at-seat menus. Also a Eurostar timetable from 1995 when there were only two direct trains per day each way between London and Paris! And a couple of Eurostar Premium First menus which came in dark blue folders.

I have not collected UK rail related literature since the mid-nineties.
