They helped to spread out the weight of the locomotive on lighter rails. CNR GMD-1's operated in my region and i've not heard any real complaints about them having an idler axle between the two powered ones.

A1A-A1As were pretty popular in NZ to keep axle loads down, DC class being the most produced kiwi diesel ever (originally built as Da class with high nose). Not super powerful, but only 15 tonne on the driving axles, a common sight all around the country, later being used on Auckland suburban services.

This locomotive is the A1A variant of U18C locomotive built for lines with low axleloads (most lines in Java are built to tramway standards back then)
After the tracks are upgraded, the locomotives got converted back to Co-Co’s just like the U18C (except 5 locos)

BNSF ordered a bunch of A1A-A1A ES44C4s on the theory that they could replace some of their older C-C DC power. They mostly work, but only in places where a high-power B-B unit would've also worked, which limits how useful they are when not racing over the transcon. FEC was the only other buyer because their mainline is another big flat racetrack like the transcon.
