Speaking of which, and at risk of venturing off topic geographically, how many rail carfloat or ferry operations are left in North America these days? I'm aware of New York harbor, the boat from the southern tip of Delmarva to Norfolk (I think that's still running), the boat from Matapedia (I think) to the north shore of the St. Lawrence River in Quebec, Vancouver Island, and the railcar barge service to Alaska. Any others?
Tom, I think you've got them all. The largest, of course, is the Alaska Hydro Train operation, an arm of Crowley Maritime. They claim to have the capacity to deliver 100 cars a week to their Whittier terminal and interchange with the Alaska Railroad. They have two large rail barges which are pulled by a variety of Crowley tugs.
The Alcoa Smelter and the Abitibi Consolidated Paper Mill at Baie Comeau, PQ, have no rail connection to the outside world, hence the operation of the rail ferry Georges-Alexander Lebel which makes an 80 mile round trip across the St. Lawrence each night. I've never been there, but its my understanding that this is a difficult operation to observe, due to its geographical remoteness and normal night time operations.
The other Canadian operation is owned by Seaspan Coastal Intermodal, an arm of the Washington Group, which also owns the Montana Rail Link, among others. This company has two ferries which are still listed as railcar capable, "Carrier Princess" and "Princess Superior". The Princess Superior is the former Incan Superior which was used to transport railcars from Thunder Bay, ON to Superior, Wisc. I'm not sure how active these vessels are in moving railcars to Nanaimo on Vancouver Island. As far as I know, Vancouver Island rail traffic has been pretty marginal for years and I would guess that most traffic comes out by truck on one of Seaspan's other ferries. These vessels and the service itself are former Canadian Pacific operations.
The other two operations, one in New York Harbor, the other across Hampton Roads, are both on life support, with great hopes for future traffic increases. Both operations use the services of contract tug and tow operators to pull railway owned barges. The Bay Coast Railway owns two rail barges and has lasted as long as it has due to railway clearance problems in the Northeast U.S. Most traffic consists of hi-wide cars. The former New York Cross Harbor is a well known operation between Greenville (Jersey City) and Brooklyn. Despite rosy projections and cash grants from the City of New York, this operation is always on the edge.
