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!
