Marshal Henry: I may be crazy but that train sounds like an el.
Cosmo Renfro: St Louis doesn't have an elevated train.
Deputy Marshal Samuel Gerard: How do you know it's an elevated train?
Marshal Stevens: I think he's right, I lived under an el for 20 years.
Deputy Marshal Samuel Gerard: Then you can explain the difference in the sound of an elevated train as opposed to a train that's running along the ground. You must have ears like a eagle, play that back, I wanna hear the sound of an elevated train.
