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!
