Ah, I see it now on the east end of the yard.
Interestingly, CP's marketing materials for their automotive capability at Saint John claim the "ability to load rail on dock" and to handle Ro/Ro vessels, so perhaps DP, Irving and CP plan to upgrade the infrastructure to handle auto racks at the dock serving Ro/Ro vehicle carriers since the existing facility at Ponderosa Yard is some distance away from the water. I note that the AIM Recycling facility is taking up prime, dockside, rail served real estate on the south end of the dock. Perhaps this operation gets moved and replaced by a higher-value auto import/export operation.
