2 lane balancer or 2 to 2 belt balancer?

Use this lane balancer when two belts each carry uneven left and right lanes. If the problem is that one belt carries more than the other, use the 2 to 2 belt balancer instead; it evens out whole belts but leaves each belt's lanes as they were. This layout uses express parts and is listed for red, blue and turbo undergrounds.

Other 2 lane balancer layouts

A corner version turns both belts 90 degrees in a 5 x 5 square. Like the straight layout it is not marked throughput unlimited.
