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!
