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!
