@¨@¨@@¨@¨@ Trains  Are  So  Constructed  That  They @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@ Have  To Follow A Set Path. This Path Is @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@ Called  A  "Railway", Which Is Comprised @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@ Of Two Metal Rails, Hence  Its Nickname. @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@                                          @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@ Because  The  Low  Friction Between  The @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@ Wheels Of The Train And  The Rail Metal, @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@ There  Are Limits For How  Acute A Curve @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@ Can  Be, And  Even More So  For How Much @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@ The  Ground  Under  The   Rails  Can  Be @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@ Sloped. Thus A Railway Is  Often Not Led @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@ On Top Of Hills,  Rather Through Them In @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@ TunnelS   (If   They   Are   Large),  Or @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@            Artificial ChasmS.            @¨@¨@¨@¨@¨

@¨@¨¨@¨@¨@ There  Will  Be Trees On The Side Of The @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@ Rails,  But Not Too Close, Or  They Will @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@ Be  Cut  Down By The  Railway  Janitors. @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@ There  Will  Be Plains,  And  Bodies  Of @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@                  Water.                  @¨@¨@¨@¨@¨

@¨@¨¨@¨@¨@ Trains  Go  By Day And  By Night.  Along @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@       The Way, There Is Information      @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@ Scattered, Often Put  On  Top Of  Poles, @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@ To Be Interpreted By  The Train Drivers. @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@ Different  Parts  Of  The  Railway  Have @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@         Different Speed Limits.          @¨@¨@¨@¨@¨

@¨@¨@@¨@¨@ Sometimes,  Trains Have To Stop And Wait @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@ For Something To  Happen, Far Away. This @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@ Is  Signaled By  Red  Or  Green  Lights. @¨@¨@¨@¨@¨

@¨@¨@@¨@¨@ Many People  Follow  The Rails By  Foot. @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@ Often This  Proves  To  Be  The  Shorter @¨@¨@¨@¨@¨
@¨@¨@@¨@¨@ Path  Between  Two Points. However  This @¨@¨@¨@¨@¨
@¨@¨¨@¨@¨@ Is  Frowned  Upon,   And  Very  Impolite @¨@¨@¨@¨@¨
