We’ve been to Oz (should that be Os?), better known outside the area as Oswestry. The Cambrian Railways Society has, most appropriately, had a base there for many years, but has struggled against the odds to operate trains much further than up and down a siding. A couple of years ago, it began running trains about 2.3km (sounds much further than 1.4 miles) down the old main line, to Weston Wharf. Here there are refreshments, in a static buffet car, and next door at the brewery tap. The train ride has a purpose at last! Today, we took a ride down the line, steam hauled by Austin 1 visiting from Llangollen (and just for the pleasure of it, we walked back). There will be a Rail Diaries entry in the next day or so, meanwhile, here’s a taster.
