title: Google maps transit_station also shows bus stations
body: <p>I'm trying to display all METRO STOPS and TRAM STOPS on a map. I'm doing so via <a href="https://developers.google.com/maps/documentation/javascript/places#radar_search_requests" rel="nofollow noreferrer">the Radar Search API</a>. It gives back all locations matching a <em>type</em> within a given radius. <a href="https://developers.google.com/places/supported_types" rel="nofollow noreferrer">These types</a> are possible.</p>
  
  <p>So I'm basically doing a search on the types <code>subway_station</code> for metro and <code>transit_station</code> for tram stops. </p>
  
  <p>The problem is that <code>transit_station</code> also returns bus stations (which also has its separate type <code>bus_station</code> so I would expect them not to be returned via the <code>transit_station</code> type).</p>
  
  <p>This is the URL I'm making the request to:</p>
  
  <pre><code>https://maps.googleapis.com/maps/api/place/radarsearch/json?type=transit_station&amp;location=51.055154,3.726752&amp;radius=5000&amp;key=[MY_API_KEY]
  </code></pre>
  
  <p>So I wonder if I'm doing something wrong or my request is simply not possible via Google Maps?</p>
