Société de Transport de Montréal (STM), the public company that manages Montreal's subway and bus system, is the second most utilized transportation company in Canada, and the third most utilized in North America, overseeing 4 subway lines with 68 stations, as well as 220 bus lines served by about 1700 buses, along with elevators, escalators and other fixed assets. But despite the crucial services STM provides to support over 416 million passenger-trips a year, the company had limited visibility to its mass transit equipment using SCADA displays restricted to the control room.
