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!
