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!
