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!
