Apply for a Job with the Railroad

Fred was applying for a job as a flagman/switch operator on the railroad. The chief engineer was conducting the interview. "What would you do if the Northern Express was heading north on Track 1 and the Southern Central was heading south on Track 1?" Fred quickly answered, "Well, I'd call my brother." The chief engineer just sat there for a second. "Why would you call your brother?" "He's never seen a train wreck before.".
