Jack is in trouble from his previous incident, but has learned his lesson, as he resists jumping in. Ned, the clumsy steam shovel, knocks the keystone out of the bridge. It begins to fall as Thomas approaches it, so Jack jumps in and tries to hold it up with his bucket.

Donald and Douglas crash into Trevor's cart and blame the other for the accident. They become so heated that they refuse to work together, so Donald is sent to work with Duck whilst Douglas continues on his own. At first, everything works out, but the two begin to miss each other.
