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!
