Hopefully RichardB will be along with some ‘official’ comment 😉
Thanks Pb. I'm not sure about "Official" but, for what's it's worth, I think there's not very much to see here. The big increases of recent years have largely been maintained and it's a very slight fall back with 52k of the 92k fall being accounted for by Plymouth and Truro. Not surprised there's been a bit of a fall back on the Maritime Line as it did suffer periods of unreliability in 18/19 (this financial year too) and the Penryn derailment happened in these figures.
I think The Tall Controller is right and I'd put it stronger than "hopefully" - main line figures will climb because of the improved services introduced in May and then fully in Dec 19 and I think that we'll see branch line figures rise too because of the increased number of connections. St Ives and St Erth will doubtless see a very big increase - Carbis Bay should do well too - off the back of St Erth Park & Ride opening in June 19 and because all trains now call at Carbis Bay. Journey figures on the St Ives Bay Line have seen a 23.6% increase since April, an extra 109,000 journeys (this is to mid Nov, the latest figures I have).
If we don't see increases across Cornwall and Plymouth too in the figures for the current year, that will be quite a surprise but, as long as things carry on as they appear to have done so far, with reliability being pretty good (touch wood), that shouldn't happen.
