Yep, it's the run-away mine train at a theme park which I visited. Sadly this particular roller coaster was closed for maintenance on the day. It looks like fun, too.

Ah, ok. It is HK Disneyland, looking over Discovery Bay. I've never been to that part of HK.

[CdM] You are soooo close, but no cigar. You are certainly right in half of your answer.

OK, got it. Ocean Park in Hong Kong. Haven't been to that part of HK either. Things about the Disneyland guess didn't quite seem right, looking at Google maps, but I assumed it was just something odd about the angle of the picture that I couldn't quite work out.

What kind of cigar do I get?
