New Jersey Transit is disputing remarks from a former compliance officer that he was let go for raising safety and other concerns.

Todd Barretta told a joint legislative oversight committee on Friday that he cataloged his concerns about the transit agency's inadequate staffing levels, failures to update outdated policies and testing practices that included giving workers answers to tests. He calls NJ Transit "one giant, runaway train."

He says he was told not to write his concerns in memos since they could be turned over to the public.

But a spokesperson for the transit agency says that Barretta's remarks are "uninformed" and "grossly completely inaccurate."

“[Mr. Barretta] was suspended for brazenly violating NJ Transit’s vehicle policy for his personal benefit," the spokesperson said in a statement.

The spokesperson also noted that NJ Transit, “has been exceedingly cooperative with the committees since they initiated inquiries about [NJ Transit’s] finances and operations in October 2016.”

Barretta was hired early this year as a compliance officer and fired in August.
