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!
