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!
