Freight conductors don’t carry coach keys.
The in train forces in passenger service aren’t lighter than freight. Sure, freight cars are pulled hard with a lot of weight behind them, but if it’s too much the knuckle lets go. Freight cars don’t go 0-80 12 times per trip and don’t have wheelslide systems that bang the cars into eachother like a Newton’s pendulum.
