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!
