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!
