The STM moves to its spring schedule on Monday. Here’s some of what bus users can come to expect:

Welcome to the Saint-Michel Express

The biggest change comes to the 67 Saint-Michel, the STM’s single busiest line, which like its counterparts along Côte des Neiges, Parc and Pie-IX will get a little brother. The 467 Express Saint-Michel takes the same route as the 67, but with only 15 stops. The STM estimates this will cut 10% off travel times (via CPTDB), thanks to the help of two McGill urban planners (thanks Dave). Other measures, such as a reserved bus lane (coming this summer) and priority traffic lights (coming in 2010), are designed to shave another 5-20% off.

The route will have 126 departures from 6am to 7pm in both directions, Monday to Friday.

The 467’s stops are:

• Henri-Bourassa
• Fleury
• Sauvé
• De Louvain
• Émile-Journault
• Robert
• Jarry
• Villeray
• Saint-Michel metro
• Bélanger
• Beaubien
• Rosemont
• Masson
• Saint-Joseph
• Joliette metro

72 extended to Côte-Vertu and Fairview

The 72 Alfred-Nobel, which connects the Saint-Laurent industrial park with the Du Collège metro, is having its route extended on both sides. On the western side, the route will end at the Fairview terminus (via Hymus), and on the eastern side, continuing on Decarie up to the Côte-Vertu metro (where all the other West Island buses stop). Service intervals will also drop slightly for this route, which operates Monday to Friday from 7am to 7pm.

Other notable scheduling changes I stumbled across

• 12 Île des Soeurs: Dramatic increase in weekday departures, which are now 23 minutes apart instead of 30 during most of the day.
• 16 Graham: New eastbound departure at 7:20am
• 68 Pierrefonds: Service intervals westbound on Saturdays drop from about 22 minutes to about 16 minutes in the afternoon, with more buses in the morning and afternoon going all the way to Timberlea/Anse-à-l’Orme. Eastbound Saturday mornings a departure is added at 8am. And for some odd reason, the 1:40am westbound departure on Saturday nights (half an hour later than the rest of the week, consistent with a later metro closing time) has been eliminated.
• 150 René-Lévesque: Weekday departures are now 31 minutes apart instead of 30, in order to remove a departure from the schedule.
• 173 Métrobus Victoria: Service intervals decreased from 20 to 15 minutes during high-traffic times (eastbound during the morning rush hour, westbound during the afternoon rush hour)
• 201 Saint-Charles-Saint-Jean: Midday Saturday service intervals drop from about 32 minutes to about 22 minutes between departures.
• 207 Jacques-Bizard: An annoying schedule quirk for this predictable (every half hour on the half hour) schedule has been partially removed. After 10pm, the departures in both directions would happen every hour instead of every half hour. Those who didn’t look at the schedule closely enough might get stuck wondering why the bus didn’t come. On weekdays, the departures return to being every half hour, but still every hour after 10pm on weekends.
• 209 Des Sources: Added departure northbound at 11:39pm. Previous final departure was at 10:55pm
• 215 Henri-Bourassa: Between 9am and 12pm Saturday mornings, time between westbound departures drops from 30 minutes to 20.
• 480 Pointe-Nord Île-des-Soeurs: Service intervals drop from 15 minutes to 10 minutes at rush hour peak
• 515 Vieux-Montréal-Vieux-Port: Service intervals increase from every 13 minutes to every 20 minutes during the day (it’s unclear if this reduction in service is a seasonal thing, as more people are expected to walk places in warmer weather, or if it’s a reaction to how little the bus is used)
