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!
