Double Crossovers

Check out some of the track arrangement here:  Complex yards

Very common on transit systems.

Real railroads would rarely use a double crossover. The center frog in that arrangement is a very high maintenance item. If a railroad needs crossovers in both directions, they would use two single crossovers. The length required for this is not a concern on a real railroad.

The double cross is more of a space-saving measure for model railroads.

Agreed, very common on a transit system to conserve space, sincerly, DCtransit

In addition, the even more modern way of railroading tends to require much higher speed turnouts/cross-overs (50 MPH to 65 MPH for example) which also require a movable-point frog. Thus, there is no way a multiple frog crossing (diamond) would be used for such higher speed cross-overs.

Thanks all.  I have the space so I will use two single crossovers to keep it as prototypical as possible.

Two single crossovers in the model railroad have the bonus functionality of crossing over and right back.  This could be a poor man's spot to park a freight car and/or have an engine run to the other end of a car to back it into a siding.
