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!
