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!
