What's that on the trackmat?

One reason to use a trackmat (I refuse to call it trakmat) is that it give the appearance of scenery, even just in printed form. There are suggestions for accessories to be placed around the train set - a great idea when trying to prompt friends or family for future presents.

This all falls down when it's impossible to identify the aerial view of some accessories.

Quiz time, what's this?

or this?

They clip in to the sides of the rails but otherwise I can offer no suggestions. The Hornby website isn't much help either as the mat shown there is different from this one.
