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!
