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!
