Eh, it's not completely obvious. I could clarify it in the OP but I'd rather not edit it as I don't think it has been yet, and it's easier to point things out as we go. This one, for example, also doesn't count. I liked this one when I came across a picture, and usually with train related sets, you can find a picture of the box, which will include the number, if you append the brand to the search.
Left one I thoght this one was fun, as we have seen that type of sign quite a noumeres amount of times by now, but never in an actual photo
I think pictures of it have been posted a few times before, actually. But not as much as the digital sign, I think! Trying to visit the page results in a custom 404, but the picture is still available!
And this picture was somehow suggested... it looks cool! It seems uncomfortable though to have to look through bars instead of a window...
I was going to share the video, but it doesn't fall within my guidelines for moving pictures (the number must be (clearly) visible for at least 90% of it, in addition to the first 5 seconds).
