After arriving from Chicago, engine #19L uncoupled from its cars and attempted to enter a switch. However, it failed to brake, crashing through a steel bumper post and concrete wall, coming to rest suspended 20 feet over Aliso Street not far from Philippe's. A 250-ton crane took five hours to get it back on the track. No one was hurt. Wiki reports that the engineer lost his job over the incident.
