## What is Choo?

Press the big “Ding Ding” button: the crossing bells ring, the gates come down and all kinds of trains come rushing by. A railroad crossing toy for little train lovers.

■ A crossing that feels real
• The warning lights flash left and right with a ding-ding sound
• The gates lower slowly and rise again after the train has passed
• Arrows (← →) show which way the train is coming from
• Press again while the bells are ringing and a second train comes on the other track
• “Clickety-clack” every time the wheels cross a rail joint
• When the gates open, the waiting cars drive across

■ 11 kinds of trains
Local train, bullet train, freight train, streetcar, express, steam train, yellow bullet train, night sleeper and more.
The more trains you watch, the more new trains appear. See every train you have met in the collection.

■ Fun to touch
• Tap a train to sound its horn
• The steam train puffs out clouds of smoke
• Tap a car on the road for a “beep beep”
• Switch between day, evening and night. At night the windows and headlights light up

■ For parents
• No account needed. Progress is saved only on the device
• Ads keep the app free. They use settings for young audiences (general-audience content only, no interest-based ads) and appear away from the train button
• “Remove Ads” (one-time purchase) turns off all ads. Buy it from “Remove Ads” at the top right after a parent check (a multiplication question)
• Plays in landscape on iPhone and iPad

* The trains in this app are original designs and are not based on real railway vehicles.
