“It’s confusing,” said a rider named Larry. “It's not even a heads-up,” said rider Tonya Henderson. “You get the notice at the last minute.”

Henderson says she’s a loyal rider, but it’s becoming increasing stressful. She says drivers seem more rushed on their routes lately. “They’re not waiting for people,” Henderson said. “They should stay for a minute, so everybody can get on and not just close (the doors) so fast. People get closed in the door.”

For its part, RTD fully admits it has a critical shortage right now. “Sometimes that means that we have to drop routes," Tonilas said.

“We have an operator shortage on the bus side and on the rail side,” said Pauletta Tonilas, assistant general manager of communications for the Regional Transportation District. “And it is impacting service at times.” RTD needs roughly 1,085 bus drivers and is 80 drivers short. Tonilas says they need 216 rail operators and are currently 50 short.
