Michel Boudreau told me the power for Saturday's ore train was CN 5343 and 5241. The same units are being used for the Bathurst switcher, as it is only shunting twice a week. The rest of the time, shunting is done by the mainline train.
He says trains 402 and 403 are no more, replaced by 568 and 569. Train 569 had CN 5373, CFMG 6909 and CFMG 6910 with no cars. They did a pickup in Bathurst and Michel heard on the scanner that they were going to work Beresford and Petit Rocher before going to Campbellton.
Here's Michel's video of 569 arriving and leaving.
