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!
