Eisner said it is up to the MBTA to pressure Mass Bay for the information.
“The T has been trying to get the information, but they need to step it up and lean on the incumbent a little harder,” Eisner said.
Keolis originally entered the bidding for commuter rail service, knowing that Mass Bay appeared to be on the inside track if only due to Mass Bay’s superior knowledge gained from running the system since 2003.
Mass Bay, which has collected more than $1 billion in fees from running the commuter rail, was founded by James O’Leary, a former MBTA general manager with deep local connections, including mentoring Richard A. Davey, the state’s transportation secretary. Davey has abstained from involvement in the selection process.
Still, Keolis chief executive Steve Townsend told the Globe last year that he felt the company had a chance to win the contract.
“We would not be investing money into this without having satisfied itself that there’s a level playing field,” he said.
Now Keolis officials are not so sure that the playing field is level after all, calling Mass Bay’s decision to withhold some information “ludicrous.”
“We may be forced to withdraw from the competition,” wrote Keolis’s Stumpf in the letter to the MBTA.
“This of course will be a result most beneficial to MBCR and a travesty of the public bidding process,” the firm said.
