That beautiful tunnel doesn't come with an AEG set; it is the old TrackMaster Morgan's Mine. Here is Thomas at Morgan's Mine set, but I believe they used it in one or more other sets:
That "mine" is actually a tunnel/bridge that can be used with Plarail, TM1, TM2, but it's too low for AEG engines, mainly because of this deep cut that can be used as a bridge when the top is removed from the tunnel:
I use it (as tunnel only, not as a bridge) on my Plarail layout, but I also used it with TM2 Toby, Philip and Thomas in THIS video.
