The wheels on the bus no longer go round and round: Raz Transportation, the local private bus company that’s carried generations of Portlanders on school field trips and other outings, has closed its doors.

The Oregonian reports Wednesday is its final day of operation, though buses apparently last ran on Friday. The closure has left customers like Portland Public Schools and the Washington Special Olympics scrambling for an alternate.

Raz Transportation was founded in 1937 by the Raz family, who sold it just eight years ago. Its last owner, Cris Schulz, says the loss of a major contract last year led to the shutdown. About 60 employees are now out of work, and 49 buses will be hitting the market.
