Pounding Mountain Set: Not Worth the Money (to me, and DEFINITELY to my Mom)

As a footnote to this discussion, I might add that the 2007 Plarail set popularly known outside Japan as Thomas at Roller Coaster Mountain (with two open trucks, and a castle on the mountain-top), and the 2014 Plarail set known as Thomas at Pounding Mountain (with a log car, and a heli-pad on the mountain-top) both have the identical name on their boxes in Japanese. The text is:

きかんしゃトーマス
どきどきマウンテンセット

The first part, きかんしゃトーマス = Thomas the Tank Engine
The last part, マウンテンセット = Mountain Set

The bit in the middle, どきどき, or doki doki, is a term used in Japanese for the sound of a beating heart, so you can see where 'pounding' came from, it's Thomas' heart pounding as he hurtles down the track from the mountain-top.

This would all have been too much symbolism for us in the west of course, so the Motor Road and Rail version of the 2007 set was dumbed down to Thomas in Roller Coaster Mountain.
