Yeah it was 45 minutes-ish when we went on - we got in the queue around 10.30 I think, but by about 12 the queue time was being advertised as 2 hours. Whether or not that was accurate is a different matter, of course.And I dunno exactly how much longer it makes it but when they made an announcement to say that only one train was running, they said it'd be roughly doubled. I think the queue was just after the second tunnel (under the first corkscrew I think) which is usually around 20 mins(?) so maybe just over doubled.
