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!
