I was watching Sherlock last week on PBS and noticed in a couple of scenes escalators. What makes me want to ask this question is I noticed the up escalator was on the left side of the pair with the down on the right. I was wondering if this was a standard in the UK. It seems to me ours are the opposite with the up on the right and the down on the left. I know its a strange question but, those are the kind I like.
