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!
