title: Specific transit service not appearing in transit layer Google Maps Javascript API
body: <p>I'm trying to display the <a href="http://www.mrta.us/" rel="nofollow noreferrer">MART</a> transit system on a web map I'm building with the Javascript API. It's listed <a href="https://www.google.com/landing/transit/cities/index.html#NorthAmerica" rel="nofollow noreferrer">here</a> by Google as one of the cities that they have transit data for, and indeed when you go to Google Maps there is bus data there. </p>
  
  <p>The transit layer example page listed here works and displays transit data for Boston, Chicago, DC, etc, but not MART. Code as follows: </p>
  
  <pre><code>&lt;body&gt;
  &lt;div id="map"&gt;&lt;/div&gt;
  &lt;script&gt;
    function initMap() {
      var map = new google.maps.Map(document.getElementById('map'), {
        zoom: 12,
        center: {lat: 42.54, lng: -71.79}
      });
  
      var transitLayer = new google.maps.TransitLayer();
      transitLayer.setMap(map);
      var bikeLayer = new google.maps.BicyclingLayer();
      bikeLayer.setMap(map);
    }
  &lt;/script&gt;
  &lt;script async defer
  src="https://maps.googleapis.com/maps/api/js?key=AIzaSyChFsvLbqcDVBUQMFQJaMxA19PhTys6ZxY&amp;callback=initMap"&gt;
  &lt;/script&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>Seems like it should work but no luck. The map appears, centered in the correct location, but no transit data for MART. If you go look at Boston, however, the transit layer appears there (as well as DC, Chicago, etc). In general it seems to be displaying train lines only but no bus lines. Any help would be greatly appreciated. Thanks!</p>
