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!
