A senior V/Line manager who was paid an annual salary of more than half a million dollars, despite refusing to provide his resume, is alleged by Victoria's anti-corruption watchdog to have also profited from a $2.2 million training scam.

The Independent Broad-Based Anti-Corruption Commission claims Alan Clifford, former general manager of rolling stock at V/Line used his senior position with Victoria's state-owned regional rail operator to involve his partner Nicola Spiers in the scam.

Covert footage presented by IBAC on Wednesday showed Mr Clifford joking about the prospect of his partner being jailed over the alleged scam, telling her it wouldn't be too bad for her because prisoners got to wear pink jumpsuits.

Mr Clifford was initially hired as a consultant at V/Line in September 2014 following a "captain's pick" by then-chief executive Theo Taifalos, the IBAC investigation heard.
