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!
