"Choo-Choo Man" and "White Head"

Treasured moments from the Brault testimony, II:

He told of an occasion when Morselli summoned him to lunch to meet a Liberal fundraiser, Beryl Wajsman, whom he was being pressured to put on the Groupaction payroll. He said a deal was worked out to pay Wajsman $5,000 a month cash, and that he delivered the first payment - a plain envelope that he left on the table while he went to the washroom. He said when he returned, the envelope was gone and nothing was said about it during the rest of the meal. He said Morselli would refer to higher-ups in cryptic terms. At one point, he referred to "the choo-choo man," whom Brault took to be an unnamed Via Rail official; Corriveau was colloquially referred to as "Tete Blanche" (white head), and the word from senior Liberals was that he should be given anything he asked for.
