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!
