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!
