The first ship dumped 300 boxes, which wasn't very much. The second one had some more and this one seems like it's going to have 10000' or more of intermodal. They typically run it over the first three days or so, but it can spread out into the week.
My understanding originally was that NBSR was going to try to run two dedicated intermodal trains two days a week in place of their manifest (so not adding any trains), but it seems the manifest traffic is taking off too. I'm told by end of summer, CP will have another pair of trains on the Moosehead, dedicated intermodal/autos, as new import autos from Europe will be coming online shortly this year. Not sure how NBSR is going to handle that....
On a more curious note, CN has also instituted its own domestic intermodal (53') service to Saint John. I find that interesting because Moncton is only 90 miles away and that facility has capacity to grow. CN is using DP World as the terminal, but those containers obviously still need to go over NBSR. I'm skeptical this service will last, but obviously a competitive measure against CP and seems as though there is a demand for it. I believe they are fighting over the Canadian Tire business, which I understand could be as many as 30 or more domestic containers a day.
CP domestic business has been doing well, last week they have 31 domestic containers on a single train, with often days them seeing anywhere from 10-20 domestic boxes, including reefers. It's mostly been all CP retail business, with some pool EMP boxes mixed in as well as Bison.
