What is grade-separate
They can't cross any other tracks/roads. I.e. everything else must go above/below it.
On one side, it can mean this. And for lighter railway construction, such as trams, light rail and rural regional trains, this can be optional. Plus it makes yards and depots easier to build, just slap a few concrete plates for a few crossings and the staff will find their way around. This is not possible with some maglev technologies
On another, it can also mean that the infrastructure is built directly on the ground. Being able to do so is extremely useful, since you don't need to build (as many) bridges or tunnels to have rail going somewhere. Again, for some maglev technologies, this is not an option.
