       Show HN: NYC Subway Simulator and Route Designer
        
       Hello HN!  As a long term NYC resident, I have read countless
       articles on ideas tweaking subway services, but always found them
       hard to follow without visual aid. So over the long weekend I
       decided to build one. It has all the basic features: trains would
       spawn at their origin, stop at stations, and slow down if it gets
       too close to another. You can also design custom routes by piecing
       tracks together.  Have fun, and let me know what you think!

       | Sometimes when I Edit Routes and click an "<- Add" button I get
       | the console error "Uncaught Error: coordinates must be an array
       | of two or more positions" and the page blanks out.

         |

         | 
         | I'll add some logic to prevent such options from showing up.

       | I can't figure out how to add a route from Bay Ridge to Clinton
       | in NJ. That's my wishlist subway - got to Newark Airport from
       | Brooklyn without going through Manhattan.
       | 
       | Edit: Actually Clifton is in NY, and playing with Google maps
       | there's ZERO public transport from Staten Island to NJ, except by
       | going through Manhattan!
       | 
       | So my idea wouldn't help anyway, unless they extended that subway
       | all the way over the Goethals Bridge.

         | more of a service designer as opposed to a track designer, and
         | it only works with existing infrastructure :(
