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!
