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!
