Hi, thanks for all the comments. I think I've figured out things - was thrown by the fact that the arctic has food rail wagons, but temperate doesnt. Pikkabird's trains go well with his UKRSI, as you'd expect. In temperate, his food factories produce goods not food, but unfortunately dont accept fish. However, I also have some other grf's, and have fisheries and food factories that do produce food. Towns do accept food. Here's my grf set cut down to the essentials
newgrf/newshipsw.grf
newgrf/cargosetw.grf
newgrf/newcargow.grf
newgrf/pb_ukrsi.grf
newgrf/nsignalsw.grf
newgrf/TTRS3w.grf
newgrf/canalsw.grf
newgrf/elrailsw.grf
newgrf/newstatsw.grf
newgrf/pb_ukrs.grf 0 3 1
newgrf/pb_av8w.grf
newgrf/tramtrkw.grf
I've got a good game going now, in temperate, thanks.
The newcargo grf, which I want for fisheries, activates the food.
A supermarket would be a great addition. Moreso, I'd like refrigerated rail wagons and Pikka's food factories to produce food.
It would be nice if town growth was stimulated by the four basics: passengers, mail, food and goods, along with "amenities" purchased by the company, with a simple single line in the cfg to replace the large number present at the moment. But that's another story.
one suggestion on the topic of food, maybe when UKRH is released have UKRSI check if its loaded and have UKRH check that UKRSI is loaded and have the food chain introduced, and then there will definately be a drop off point for food.
