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!
