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!
