Gary Lee and Dave Dineen both taped the same train, NBSR 9802 East, from McAdam to Saint John on November 21. Gary caught it leaving McAdam and Dave picked it up at Vespra (near Tracy) and chased it to Westfield before night fell.
Here's Gary's clip showing NBSR 9802 and 2317 leaving McAdam.
The rest of the story is told here, in Dave's excellent video. Here is his description of the chase.
EDIT: Added link to Dave's commentary.
