I see how a turnout can be laid on a bridge. Now to figure out how to throw it. I do not want to power it. I would like it to be thrown by hand manually. I am using caboose throws on other turnouts.
Great notes. I appreciate the responses. I'm getting the picture.
If you want to see lots of prototype turnouts on bridge structures, just check out Broadway Lion's posts. Alternative plan, use Google Maps to look at his prototype (Enter Westchester Avenue/Tremont Avenue, then follow the elevated northeast.) Of course, all that specialwork is located on deck girder structure.
I have built turnouts on grades, including one on a superelevated curve and one on the concave transition between a 2% grade and level track. As long as the three-dimensional geometry of BOTH routes exactly follows what would be there if each route was laid with plain flex track, no problems. OTOH, I wouldn't try the same thing with products bought in a hobby shop.

A long car taking a diverging route through a switch on a through-type truss or girder bridge might overhang enough to strike the structure members. Plan ahead and make sure proper clearance is provided.

I have numerous turnouts leading to siding and stub tracks where there is a 1.5% downgrade (1/8" in 8") immediately after the turnout and one turnout where there is such a slope both before and after the turnout. I have never had a problem with these whether running 40'-50' freight cars or 85' passenger cars, 6-axle diesels or a 2-8-2 Mikado. Track and turnouts are Code 83 Walthers/Shinohara.

P.S. I tested this before applying it to the layout-it wasn't blind luck!
Thanks.
On grade is possible but there can be no change in the grade from one car length before the switch or one car length after the switch. Perfectly flat does it. Bridges should be possible, but again, perfectly flat is the key.

Using turnouts on inclines and bridges. Has anyone laid a turnout on a bridge, double truss? Or on a incline/decline?
