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!
