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!
