• The product is Tube
• The channel is tube:northern:940GZZLUEUS:arrivals which corresponds to Euston Underground station NAPTAN code, for the Northern Line. Find more station NAPTAN codes.

let ably = new Ably.Realtime('YOUR_API_KEY');
let channelName = '[product:ably-tfl/tube]tube:northern:940GZZLUEUS:arrivals';
let channel = ably.channels.get(channelName);
channel.subscribe((msg) => {
  /* station update in msg */
});
