A train without rails

This day is filled with fun when most of the KIDSPACE children experienced a train journey unexpectedly. They got ready to take their turn to enjoy a long trip along the stoney pavement.

But among the stones the train ceased to move. There was serious discussion on it for about five minutes. Soon they reasoned a train needs rails to run on. Donnagh and Joshua got out to remove the stones from under the wheels. All became happy when the train started to move again. Mohanan
