And from a senior manager at Scotrail in response to "Languishing in Largs [Day 8]" (read again)
The 398 does run!
Meanwhile, in the bowels of the earth, the sign for the inter station bus directs you westwards ...
Buses run every 10 minutes from 0800 Monday to Friday and 0900 Saturday until 1800 then every 20 minutes unti just after 2000. On Sundays the frequency is every 20 minutes from 1200 with a two hour earlier start during the summer months. The times shown in orange should convey the latter nugget of information, but the text in the matching orange "note strip" is incomplete and gibberish, so you might end up with a two hour wait!
To improve loadings, fbb has a few suggestions:-
If it is an SPT route, then maybe ask them to publish the timetable?
Just one caveat. The existence of this service MAY be revealed in some of Scotrail's excellent printed timetable leaflets and booklets; which is better than nowt. fbb did not have any "hard copies" to hand but discovered this, on-line as a by product of looking for something else.
