The problem with the pre-built crossing is the amount of plastic used to keep the power isolated. In the Wabash/IC crossing that has 5 in a row it amounted to something like 3 inches of dead space in 9 inches. This causes a lot of 4 axle engines to stall.  With hand built the issue goes away.

Forgive me folks but that’s not a crossover...that’s a crossing. A crossover requires two parallel tracks and two
turnouts. By the way Peco makes much nicer crossings.

Lee, why not build your crossover with isolated corners where opposite rails intersect.

No need for a reverser or juicer. No problem with power districts.

Look at the design of an Atlas crossover:

All, I am referencing David Klemm's scratch built diamonds ( he made for his DCC layout.

I fully understand  his diagram, but on our club layout the two tracks that cross are on different power districts.  Will this be a problem in hooking up an auto reverse circuit or a frog juicer?

Thanks much in advance.
