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!
