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!
