Passing Trains

'Since the track from here to Los Angeles is three times longer than that to Chicago, the chances are three to one that the train is to the west rather than to the east of you. And, if it is west of you, it will be going eastward the first time it passes. If there are many trains traveling between Chicago and California, as is actually the case , the situation will , of course, remain the same, and the first train passing our city after any given time is still most likely to be an eastbound one. ‘

既然从这儿到洛杉矶的路程是到芝加哥的三倍,那么你遇到西行车和东行车的比例是3:1. 如果它是相对你西行,那么它第一次经过这里时必然是向东的. 如果芝加哥到加利福尼亚之间有很多火车行驶,事实也如此,结果还是一样,在某个时间后通过我们镇的第一列车仍最可能是向东行驶的.

the chances :〔C; U〕可能, 可能性

after any given time: after any fixed time
