I visited Manchester last year for the first time in many years. It seemed remarkably easy to pay for the trams, simply by touching in and out using contactless. What am I missing that is so hard?
It's not hard at all, of course, but every system's different, so on first use it requires some research to understand what to do. For example, in London you generally need to register your card to get a receipt; in Manchester you can't register your card and you don't need to. You also have to tap out after using Manchester's trams, unlike in London. So it just takes a couple of minutes before using for the first time.
I don't use Metrolink very much and I only used contactless for the first time in January, it worked fine of course and now I know exactly what I need to do.
But if I went to Nottingham I'd be confused unless I'd done some research in advance, for example.
And don't get me started on bus fares - I understand London so I use them there but I don't know what the fares are or how exactly to pay for the one that stops at the end of my road in Wilmslow. If I wanted to use it, I'd go and look it up first.
EDIT Wasn't this some of the logic behind the ITSO card, which only seems to be usable in some places still, so isn't worth bothering with in general - if it were accepted on just about all types of public transport that would mean that I wouldn't have to worry about turning up in Nottingham and using it on a tram. At the moment I'd have to do my research to see whether or not I could use it, which kind of defeats the purpose.
