Rails                  
                                          
                                          
  
                                          
  
                                          
                                          
 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 
         Toward The Train Drivers!
