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!
