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!
