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!
