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!
