Yeah, why on earth would they shove "Rail" into that name? I'm sure it makes sense internally, but as external name it doesn't make much sense. None of the people are even using the rail/train analogies that are right there, then what's the point even?!

> "Payment rail" is a very long established term og art.

Yes, by all means, use the existing terms internally, but when you launch things, remember you work in somewhat of a bubble, and figure out names that make sense to people. 99% of the people aren't gonna know about "payment rails", and when they hear "rails", they either think about trains, or they're a programmer and starts thinking about Ruby. And then of course there is a third group of people, like the ones that say "Payment rail is actually an established term".
