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 
 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!
