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!
