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!
