double crossover

[ozzy]

ok, im looking for a double crossover. the only ones i have found have the plastic roadbed on them, im using atlas fextrack code 80. i cant find any made by atlas online .

anyone knows where i can find one for N scale?

I don't know about Code 80, but Peco has one in Code 55.

Maybe you can use some rail joiner adaptors to link the different code rails.

whats an " electro frog" ?

I see you've been looking at Peco turnouts. An "electrofrog" is a non-insulated frog. That means that it's live all the time. This is good because there are no "dead spots" in the track. It's bad because you're more likely to have a short circuit in the point rails, and you'll also have to isolate the two rails coming out of the frog. They are also not "power routing".

looks like they cost some big bucks for one piece of track. i wonder if i can do the same thing with 4 switchies.....


all i want to do is run 2 mainlines where i can change ether train back and forth between lines if i want without picking them up off the track.

They end up being a bit larger, but you can assemble your own with a crossing and four turnouts. In HO scale using Atlas code 100 I used two #4 lefts and two #4 rights and a 25 degree crossing. It requires a couple short straight pieces for main line between the turnouts but places the two main lines 3 inches apart. Surely the same can be done with N scale.

Using XTrkCAD I made one with Atlas N scale. There isn't a 25 degree crossing, but the 20 degree works with #6 turnouts. Comes out to 2.25" centers and 17.15" long.

Ah ha! While writing this I tried it with a 30 degree and #4 turnouts. Works! 1.9" centers and 12.3" long.

so if im using a differant transformer for each line, id need to use the plastic track conectors in there somewhere right? on both rails of the track?

and if i want to have a sidding with a train waiting to pull out to the mainline using one transformer i just need to use a plastic connector on one rail with a jumper for the power with a toggle switch right?

id like to have a train pull into a yard, then unhook the mainline engine, and then pull out with new cars, then flip a toggle to move out the yard engine to break up the train that just came in.

If you have room use two single crossovers, which can easily be made with standard switches, and are more prototypical anyway.
