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!
