Good Day,

I am in the planning phase and have a smaller (18'x5') loop of 42" radius Gargraves that will be the initial focus of the layout.  I have a longer running loop of O72 (32'x11).  I do not want to do a crossover switch as I'd like the loops to join with enough distance to add a station siding on the O42 loop that is long enough to fit a six car passenger train.  Thus, the #6 and #8 switches are too long.  Would I be cool to do this with two pair of 11 degree or #4 switches so long as the train is not at full speed upon hitting the switch? Should I go with a radius switch option, or find another spot to try this entirely?  Thank you for your thoughts on this.

We could probably advise you better if you would post a diagram of your layout, or even a carefully-drawn sketch.  That being said, you probably wouldn't go wrong with the "regular" 11-degree turnout.  The switches with a curved leg often result in 'S' curves or abrupt transitions to restore parallel alignment.  Thankfully, Ross gives you lots of options!

I estimated that you need about 100" for a semi-scale steamer and six car train. You have about 150" of straight to work with in the O42 loop. The Ross Reg 11° are 14.65" long or 29.3" total. 

Placing the switches in the O42 loop just past or at the curve will give you the maximum straight to work with.

The 11° can handle a good speed for crossing over.

here's 12- GG 10"
