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!
