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!
