Thomas & Friends - Season 10 Episode 15 Which Way Now?

Rusty is very hasty, and tells the workmen he is taking around to get their direction sign painting done as quickly as possible at the various locations. Rusty then takes the Fat Controller and his family down the line for a walk around the mountains. They are supposed to meet him back at the tea rooms, but when they do not return, Rusty grows concerned and goes out of his way to look for them. When Rusty finds several people at all the wrong places as he goes along, he realizes that it must be the direction signs that are causing all the bother!
