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!
