Do the numbers that are fixed to the ticket gates (just below the place where the tickets are inserted) have any relevance, please? I've seen various numbers on different gates and, whilst they may be consecutive, the don't bear any resemblance to the platform numbers or the number of gates on a station. For example, there are six gates on Newport station serving four platforms, but the numbers on all of them are in the 90's rathe than being one to six. Cardiff Central also has a similar numbering system, although they have more gates, more platforms and their numbers are a different sequence. It's something I've always been puzzled by ... can anyone help, please?
