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!
