Well all I can say at the moment is the next train to arrive will be...arriving at some point. I can't say when and I don't really know yet what it will look like when it does, but at least, for the moment anyway, I'm pretty sure where.

Yes, as far as I'm concerned, the next train to arrive, will be arriving at St Germans Quay. It will have set off earlier in the day from somewhere in the westernmost reaches of East Cornwall, Liskeard possibly, or maybe on a shorter run from Menheniot. It will have busied itself for a while at Trerulefoot Junction, awaited the passing of a through or two bound for Penzance or Plymouth, then set off diverging hard right and down, seemingly with designs on Looe before revealing more modest intentions with a continued, curving descent to Polbathic. A brief stop, hisses, creaks and birdsong, then on again, hugging the creek almost at water level, the wooded valley rising opposite whilst ahead the broadening lake marks the joinging of three rivers ahead, and journey's end.

A final tight curve, the outskirts of the village just visible on the hillside, and then the view is dominated by the towering spans of the viaduct, right across the valley, high above and carrying Castles, Halls and Counties on other prestigious business. Meanwhile down below, a more modest and ramshackle piece of railway forms our terminus: a single platform, clinkered sidings and crumbling quay wall.

Time to run round, take water, prod lethargically at a few grubby wagons and then back the way it came. To be repeated, with a few variations, until the inevitable axe falls.

But if it's going to arrive at all, I'd better get building.
