Sorry to perhaps drift off topic slightly but I thought this may be interesting. Do some of the new timings do the upgraded infrastructure and electric traction justice compared with previous years? As there are of course more station stops and frequent services, it's not exactly like for like, but here is a scan extract of the 1987 timetables for Blackpool Preston Wigan Liverpool Manchester.
To put into context 142's had recently been introduced on the new hourly Preston - Liverpool trains. (previously from 2-3 a day) Other services were class 104 and 108 DMU's, and some new class 150's shown by the S symbol. Parts of the routes still had semaphore signals and jointed track as well.
1hr 25 from Blackpool - Liverpool in a 142, and a 1hr 12 from Blackpool - Manchester - in a class 104!
Also, see how many new stations have since opened. Salford Crescent was just open, but seemingly not yet part of the link to Piccadilly.
