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!
