Staffing Shortage Forces Temporary Schedule Cuts

MISSOULA, Mont.—Due to an ongoing staffing shortage, Mountain Line began a temporary service modification on Monday, April 3, affecting bus frequency on Routes 8 and 12.

Instead of running at half-hour intervals during peak demand hours in the mornings and late afternoons, both routes will run hourly, allowing 10 employee hours per day to be reallocated and relieving the strain on the current workforce.

Additional service modifications affecting Routes 1 and 2 are scheduled to begin on April 16. Instead of a 15-minute service frequency, Routes 1 and 2 will run at 20-minute intervals, meaning some riders may face slight delays when waiting for connecting routes.

These reductions are expected to last for at least three months and possibly through the summer. No other route or service changes are planned, and Shuttle Van and Paratransit service will continue normally.

Mountain Line has been actively recruiting new bus operators, with a new class to begin training on April 17. In the meantime, temporarily modifying schedules allows the company to continue service without overburdening bus operators and dispatchers.

“The last thing we want to do is cut service,” says Director of Operations Jennifer Sweten. “We tried to hold off as long as we could. But with so many employees out sick during flu season, and a continuing labor shortage, we just had no choice but to relieve the pressure on our current operators.”

Revised schedules for Routes 1 and 2 will be posted shortly; schedules for Routes 8 and 12 are up to date on the Mountain Line website: Maps & Schedules – Mountain Line. The Transit app will be updated with new schedules before Route 1 and 2 changes take effect in two weeks; in the meantime, riders are advised to verify schedules on the Mountain Line website directly and watch Mountain Line’s social media channels for any updates.
