I am researching how Edinburgh to London daytime services have changed over the years for a possible article. I am looking for information on services in the 80's in the HST era and in the 90's in the electric. Alas, my copies of the GB all line timetable for those periods were disposed of by Senior Management when we were having a clear out, on the grounds that they were superfluous.
If anyone has copies of timetables in the 1980's and/or 1990's, I would be interested in the following from table 26:
1.how many daytime trains were there from London to Edinburgh, by which I mean not sleeper trains?
2. What were the typical journey times?
3. Was there any pattern to the services, ie, were they regular interval?
Any help gratefully received. Many thanks.
