Sort of. I bought one and tested it and considered that with another it might do, but it would have cost more than the one vacuum I bought and still had only about half the vacuum power.Neat solution, Lee.
Question: Did you consider buying two HO vac cars and mounting the guts side-by-side or staggered on a suitable flat car to provide the necessary width? You'd have no difficulty fabbing a suitable housing.
I like your solution; just wondering if the HO units would lend themselves to this alternate approach?
