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!
