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!
