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!
