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!
