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!
