No #8 won't be running, #7 probably won't be finished this year, either. The boiler work will probably be done, but there are a LOT of parts that have to go back on in the order that they came off the frame, beginning with the boiler.
Baring any new developments, however, #4 will be back again this spring, ready to haul happy families up and down the Eastern Promenade in Portland.
