SINGAPORE, May 22 (Reuters) - Shares in Singapore's public transit operator SBS Transit Ltd SBVV.SI soared to a two-year high in early trade on Thursday after the government announced plans to overhaul the public bus operating system.

SBS shares jumped as much as 12 percent to a two-year high of S$1.59. Shares in ComfortDelGro Corporation Ltd CMDG.SI , which owns 75 percent of SBS Transit, edged down 0.4 percent.

Under the new model, the government will own the buses and appoint routes and contract the service to operators, Singapore's Land Transport Authority said on Wednesday.
