I must have been about 9 or 10 when my parents took me on the first "Excursion train" that I remember. I presume it started at St. Helens Shaw Street, but we joined at Moss Bank (on the Rainford branch), and went to Southport. I don't remember the route details, but it can only have been via Ormskirk (reverse, loco ran round train) and Burscough South curve. Non-corridor stock, and a rare loco for the Rainford branch, Jubilee 45623.
In later years, did several ADEX / MYSTEX organised by Liverpool Division, which - dependent on route, usually picked up at Runcorn or St.Helens (Shaw St. or Junction). One of the last involved 40111 to Largs and back. Surprisingly not many enthusiasts going North, as the "40 bashers" hadf expected it to be electrically hauled over Shap.
And two I remember whilst working in London, both from Finsbury Park; one a Brush 2 (Class 30) to Southend Victoria, the other a Class 24 (D5052) to Brighton (via York Road & the Widened lines). (Their TOPS classifications are shown to help identify the locos, but did not exist at the time of the trips).
