Sadly, no longer at the Cholsey and Wallingford Railway and 'preserved' in only the vaguest sense.
After the locomotive arrived at Wallingford (without the C&WR knowing it was coming!), two friends and I were offered the chance to purchase it for a "nominal sum". We set about looking for a permanent home for it and eventually decided that the best course of action would be to try to persuade Reading Council to purchase the loco instead. Our contact at Reading Museum Services was very enthusaistic, but the "elected members" less so, at least in practice as every decision seemed to get delayed from one meeting to the next. They did however provide £300 for a condition report to be carried out by an engineer from Quanton Road who gave us a quotation for a cosmetic restoration. We took that back to the Council, who continued to look for a location to put it on display once the work had been carried out. Eventually the Council rep called me to say he'd found somewhere it could go (we never did find out where though I have my inklings it could have been near the North Entrance of Reading station) and could we meet up, but the day the meeting was due to take place, the Readign Post rang me with the news it had been sold elsewhere (for £20K!) - to a Yorkshire farmer as a 'surprise' for his father, who expressed an intention to restore it. He invited us to come and stay in his B&B if we would like to help him, we sent him a copy of the condition report and said "Get the asbestos out and we'll talk about it" and heard nothing since. Google images seems to show it languishing in the middle of a scrapheap and we've heard a rumour it narrowly avoided being blown up at one stage as another of the farmer's surprise presents was a pile of unstable WW2 ammunition!
