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!
