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!
