I've been putting in some time on the Brown Line in Chicago, adding detail to the stations and plugging in the Public Transport[1] tags. I'm pretty much done with it, and I thought I'd throw it out there to see if anyone has any comments. The Overpass diagram generator seems to like it [2] [3] but the PT tag system is kind of complicated and I may have missed something.
One specific question: Since the Brown line is a loop at one end, it doesn't have two defined terminals, although it definitely has two directions (towards Kimball and towards the Loop). Does anyone have any guidance as to where the two route relations should begin/end? As it is I set Merchandise Mart as the final station for the Loop-bound train, since the operators usually change the train's destination sign to "Kimball" after leaving the Mart. Likewise the first station for the Kimball-bound relation is Washington/Wells. Maybe I'm overthinking this, but if there's a standard way of treating routes that loop back on themselves, I'm unaware of it. Lastly, I doubt I have the patience to update the whole CTA system, so if anyone else has an interest in pitching in, go ahead. I know there are at least a couple more Chicago-area mappers who ride the L. The USGS Large-Scale imagery in Chicago is very detailed and more recent than the highest zoom available through Bing.
