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!
