The New Brunswick Southern Railway is using MMA 2000 in New Brunswick and Maine. I don't know the details of the arrangement, whether it is a long term lease or a short term loan, but the MMA 2000 has been working in the McAdam yard and on work trains fixing up the flood damage.
MMA 2000 is an ex-Conrail GE B-23-7 engine.
Rumour has it that MMA 2000 has gone to Saint John but I have no confirmation of that yet.
Here's one more shot of MMA 2000 in McAdam with NBSR 2610.
