Trains

Train Ethan, George and Vera need to get to the other side of the river. But they found that the construction of the bridge is suspended for an indefinite period. Ethan had an idea to build a float. And when the float was ready Ethan had to work as a ferryman. There were so many people wishing to cross the river, that exhausted Ethan was able to return to his friends only after the bridge was built.
