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!
