 However, numerous interventions, such as the installation of public telephones and loudspeakers, with visible wiring, have had a significant impact on the elegance of many stations.Along with the Stockholm Metro, Montreal pioneered the installation of public art in the Metro among capitalist countries, a practice that beforehand was mostly found in socialist and communist nations (the Moscow Metro being a case in point).More than fifty stations are decorated with over one hundred works of public art, such as sculpture, stained glass, and murals by noted Quebec artists, including members of the famous art movement, the "Automatistes".
