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!
