Planning continues on the Acadian Railway project. I received an update yesterday and I'll pass along what I can.
Route selection is still ongoing. Initially a rail barge was planned to Lameque but this has been replaced by an intermodal transfer facility. Chances are the route could change again before it is finalized this summer. Route selection is a tricky business. You have to try to connect to the most shippers possible, while minimizing cost and doing the least damage to the environment.
As I mentioned the planners are looking at EPA Tier 2 locomotives to achieve good fuel efficiency and minimize the effect on the environment.
I'm not sure what else I can pass on yet but I'll try to keep you posted.
