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!
