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!
