Actually I said the wrong thing, I meant a class 1A inspection, which is required any time the consist changes. If said equipment might fail that test, you don't want to be on it. I agree you'd want to keep the stuff on house air and power but that's not going to get you out of conducting the required tests. There's always the chance of a fluke, but you're typically not going to discover something after putting a train together that was not discovered in the previous maintenance inspection. Just like the required brake test every time a train changes ends, I've never seen one fail on the road. When I have seen it fail, it's been a valve or cut out cock improperly set.
