And now, Words and Their Stories, from VOA Learning English.
On this program, we explore words and expressions in the English language.
We give examples and notes on usage.
And sometimes we tell you how the expression came into use.
Today we talk about train tracks.
Imagine a town that has a railroad and train tracks running through it.
Trains may be great to travel on, but crossing their tracks can be dangerous.
Bright lights and warning signals at tracks can only do so much.
Train tracks often will divide a town in two.
One side is often more desirable than the other.
