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!
