Plow 68 work. These photos and story are from Cam Sargent. Another successful day of repairing/restoring equipment at the Bartlett Roundhouse today! After a rainy start, Pete Davis , Bob Marshall, and I began removing more of the old sheathing boards from the woods side of Portland Terminal snowplow #68. By lunchtime, the weather turned in our favor, and we finished installing the new sheathing boards, and Bob caulked the seams. The next step will be to ad the quarter-rounds to the edges and finish caulking them. Then a primer coat, and a green paint coat.
