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!
