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!
