Ross Switch 072-054

What feedback do you want?  Stuff requiring O72 will run through the O72 leg but will derail on the O54 leg.

They probably want to know how reliable the switch is.

And by that, I mean that I want to know how reliable the switch is are there common issues that need to be accounted for? For example, the double slip switch seems to prefer slower speeds but otherwise works wonderfully for average locomotives and rolling stock.

In the 3-rail world, we have swiveling, truck-mounted couplers, and blind wheels on long-wheelbase locos (and even blind center wheels on 3-axle diesel trucks). That means that, if you have a radius restriction, the reason is probably not because the engine or car is "too long" to get around the bend. Probably, the restriction is because, on tight turns, the trucks will strike some part of the engine or car as they swivel. This problem which will exist on a too-tight curve, even if it is only a few inches in length.

So, probably, no, you are not going to get away with it. Not on the O-54 leg.

Just because a turnout starts at a certain radius. Your not committed to it throughout the length of the curve. In your upper left corner I’m seeing a curved switch which looks like it leads to a passing track. Looks like you are using all sectional track. Ross offers a larger curved switch which has an 072 diverging curve and an 096 main curve. You could use this as sort of an easement. Yes it will stretch the layout a bit. You will probably have to lay the curve with flextrack. But you can tighten up the radius as you move into the curve and up with the same radius at the other end. On the inside trackage. There’s a big difference between an 054 curve and an 072. Ross offers I think an 064 and that may work for what your doing. Again you need flextrack. But you can leave the trackage a bit closer to ease into the radius you need and just put something like a Yard Limit sign at the point you have enough clearance between tracks for when you have something sitting idle on it.

The Wye looks to feature a couple of curved turnouts. Same thing applies. But again you are stretching the layout with a bit more room needed you may not have.
