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!
