After a few terrifying collisions with impatient truck drivers in the early 1990s the PV&T started to rebuild some of the ancient class B motors with canadian-style safety cabs. Since this work was done by the Portland shops, this meant that the cabs were streamlined something like an EMD F-unit instead of being a prismatic block (as ILW and every other locomotive manufacturer in North America was doing.)
215 was the first motor completed in the spring of 1992; It came out of the shops in a B&Q-inspired streamliner livery, which was then used on most of the rest of the Portland BCC rebuilds.
