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!
