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!
