The love story of the railway Turnout
Do you have the idea of switch and crossing?
Here is the answer : Switch and crossing, a kind of line connection equipment turning the rolling stock from one line to another one, is usually laid massy at the station or the marshal-ling yard. With the assistance of switch and crossing, the passing capacity of lines can be greatly improved.

Next let us enjoy the following esthetical love story:
He and She
A pair of good friends
Two parallel lines
Extend on the road of their each life
He and she
Having thought there would be no interaction for them
Living naturally and unrestrictiedly in the world of mortals
Sharing the prosperous social lives and pentium forward
Turnout, the naughty guy
Break up The parallel lovers
Let true lovers fall in deeper love
Let false lovers part company
Got it? That is turnout, one reasonable thinker doing the job of separation and reunion.
