title: How to display all available routes on an embed map with Google Maps API?
body: <p>I'd like to know if it's possible to show all the available routes using public services (like trains or buses) between two points and be able to choose one to see more details in an embedded map using the Google Maps API (Embed of Javascript) like using the Google maps website itself (<a href="https://www.google.es/maps/dir/Utrecht+Centraal,+Stationshal,+Hoog-Catharijne+CS+en+Leidseveer,+Utrecht,+Pa%C3%AFsos+Baixos/Concordiastraat,+Utrecht,+Pa%C3%AFsos+Baixos/@52.0917628,5.1022163,14.5z/data=!4m14!4m13!1m5!1m1!1s0x47c66f5d6556b979:0xb88d703d634c4d6e!2m2!1d5.1101691!2d52.0893191!1m5!1m1!1s0x47c66f6d791d1c53:0x448d692110ae252b!2m2!1d5.0983096!2d52.0996097!3e3?hl=ca" rel="nofollow">Example</a>).</p>
  
  <p>As far as I concern, I can only embed a map with just one specific route, or a global map, but not one with all of them and let the user choose which one prefer.</p>
  
  <p>Thanks!</p>
