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!
