      The core portion of Montreal Métro was built in 
      anticipation of the city's Expo '67, and thus by now it is a fairly old 
      example of the "new" urban subway system.  Some of the four lines 
      have seen moderate expansion during the ensuing decades. 
       
      One of the more unusual features of the Métro is its 
      use of rubber tires, in the fashion of much of the Paris system.  The ride does indeed 
      seem different, and the guideways present an unusual appearance to those 
      used to more conventional technology.  The rubber allows for better 
      negotiation of grades and quick acceleration and braking.  It is 
      supposed to result in a quieter ride as well.  Somewhat visible in 
      this photo taken at Berri-UQAM, standard steel rails, available for use in 
      emergency situations, also are present, inside the guideways.   
       
      Downtown stations are linked to an extensive system of passageways and 
      corridors, and a multitude of underground shops and services.   |
