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!
