No racing in the haul-ways! A look at seven adorable train cars on their first day of school.

All aboard! A new line-up of students is off and rolling to Choo-Choo School. After reciting their classroom rules - Work hard, play fair, be kind - it's time for some maths to get the wheels turning. Then everyone's ready to climb a hill in PE (it's good to blow off steam), sing songs in music (Flat Car is a bit off key) and learn the whole alphabet, especially the letter R.

Bouncy verse portrays a world where train stations are classrooms, the conductor doubles as teacher and Boxcar is happy to hand out tissues to anyone who ah-choo-choos. Bright, energetic illustrations by animation artist Mike Yamada bring the whole clickety crew to rollicking life.
