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!
