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!
