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!
