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!
