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!
