A Train With No Name

While exploring the circus train that came to town, your child finds some old uniforms near a little track tester.  The poor track tester doesn't have a name or an engineer which makes him very sad.

When the circus train is leaving your hometown, the train with no name is last again.  Suddenly, an alarm sounds.  One of the rails is loose, and the circus train could crash!  Your child quickly repairs the track tester's whistle so that he can warn the circus train. 

Because of their heroic actions, the train with no name gets a name, and your child gets to be his engineer!
