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!
