" ...typical for some longer haul train links, airport trains with underground sections like the RER etc." I am certainly aware of the frequency most subways run at, that's why I clearly defined a comparable system, and later in the post underlined that Loop is not a direct competitor with subways but with above ground light rail. I have no idea why people get triggered so easily and jump to type out a response without finishing reading the post - or, in this case, the sentence - they are replying to. It must have something to do with the compressed attention spans that come with smartphones.
