 Exciting things are happening at Traymasters TV. If you haven't been tuning in, here's just some of what you've been missing. In the Back Shop Clinic, Joe Fugate has tips for making your layout run like a dream. So here we go, 24-inch radius curve, a 50-foot car and 80-foot car, and I try to couple them, and you notice it just doesn't work. It isn't going to happen, and even if I try to pull a coupler over, it's not going to happen. Crew call goes deep into the world of prototype operations with Bob Bellowfield's CP Rail Golf Subdivision. The double O-D, the train with the name of three letters, the double O-D stands for Oshawa, Oakville and Detroit, and what this was, was it was a train that was very heavy in auto parts, and it would service the auto industry, and it was a fairly hot train. On Not Chained, Pierre Oliver decipheres free car lettering. And then the lightweight, of course, is the empty weight, and that's the key here, when you roll that thing over the scale, you subtract the lightweight from the actual weight that's on the scale, and that's what the customer gets built. So these numbers change over the age of the car, and that has to be kept up-to-date and accurate. On our project layout series, start small, think big. Ed Wilson from NCE and host Miles Hale wire a module for DCC. This single button will control the turnouts. It will throw out either normal or reversed. That's correct. And one reason we did that is because we have some small grommets like this that we're going to mount into the fascia. Our bench work here has these pre-done holes, and these will snap right into that. And ESU low-sounds Matt Herman demonstrates function mapping on our DCC-decoded segment. So as that finishes up, we'll click into the driver's cab, and we're going to press go. Now as we watch the headlight of the front, we'll turn it on, hear that dynamo spool up. Now, because I'm sitting still, it's one brightness. Right. Once I start to move, you'll notice how it comes up in brightness intensity.
