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!
