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!
