Hmm, the text behind the "View all by enerQi", "Follow EnerQi", etc are the 2 buttons you need. First is to send the train and the second button for creating the train.
Curious that full screen didn't work (full HD resolution?) . I did upload a second version (canvas resizing, so the UI is bit better) but didn't work :(. I'm using Edge, so this is also a chromium browser.
