Truck and bus fleets work quite well and at lower cost using natural
gas as opposed to #2 diesel.

That's some low hanging fruit to get started.

Waterloo regional transit had a fleet of natural gas busses, and the
maintenance costs totally killed the project - they went back to
deisel, and now have quite a few hybrid deisels. The extra engine
maintenance on the CNG busses outstripped any possible fuel savings.

I am seriously curious as to why maintenance costs were higher. Do you
know?

Since CNG engines outlast gasoline engines, I'm willing to bet that it
was the switch from diesel to CNG IC engines which caused the
maintenance shift.
