Frisco Rumble

S1, E5: The mice visit their cousin Ernestine and her friend Jeannie and discover that the famous cable cars are mysteriously breaking down. Jeannie's grandfather invented the cable cars, but her father, Jamie, can't figure out what is causing the problems. After a near crash, he fires Murphy, a brakeman with a bad attitude. Murphy disguises himself to look exactly like Jamie and proceeds to rob a bank. The police grab Jamie and charge him with the robbery. Meanwhile, the mice discover what's wrong with the cable cars. The rats are moving out - throwing their garbage everywhere and clogging the cable because there's an earthquake coming! (Rats are very sensitive to seismic activity.) The mice and Jeannie catch Murphy and deliver him to the police, while warning the townspeople of the coming earthquake.
