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!
