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!
