developed for the Paris Métro; Montreal's system was the first in the world to be entirely rubber-tired (as not all of Paris's lines use tires). The Metro system is Canada's busiest subway system in total daily passenger usage; in 2017, serving an average of 1,235,200 daily passengers on an average weekday; a figure which surpassed that of the Toronto subway and Vancouver SkyTrain. In 2016, 354 million riders (transfers not included) used the Metro. Bus services The STM bus service operates well over 200 bus routes serving a number of different markets. These routes serve an average of 1,403,700 daily passengers each weekday. Local network routes, numbered 10–299, generally operate seven days per week, from 5:00 am to 1:00 am. Some routes offer decreased services on weekends and holidays. Within this classification, some routes operate only at peak hours Monday through Friday, and sometimes only in peak directions. The Navettes Or, numbered above 250, are specifically designed to serve the needs of senior citizens. All-night network routes, with route numbers from 300 to 399, generally operate from 1:00 am to 5:00 am, seven days per week, at a maximum headway of 45 minutes. Some routes offer increased service early on Saturday and Sunday ("late" on Friday and Saturday). Express Network routes, numbered 400–499, are limited-stop routes. Some routes are classified as Metrobus, and Trainbus and are geared to deliver commuters to specific Metro and commuter train stations, although these designations are no longer in use. Most Express routes operate only at peak hours Monday through Friday, and sometimes only in peak directions. Shuttle Network routes, numbered 700–799, are special-purpose routes serving Canadiens hockey games, tourist areas like Old Montreal and La Ronde, as well as the 747 route running 24/7 between downtown and Montréal–Pierre Elliott Trudeau International Airport. On August 30, 2010, the STM introduced the "10 Minutes Max" network. This network, overlaid on both the local and express networks described above, schedules buses at a maximum headway of 10 minutes, between 6 a.m. and 9 p.m., Monday to Friday, on 31 of the STM's busiest bus routes. A few routes support that maximum headway only in the customary peak direction mornings and afternoons, while some routes outside of the advertised network attain similarly short headways but within shorter periods. However, on January 6, 2023, the STM announced it planned to permanently end all "10 Minutes Max" routes due to
