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!
