Waterloo regional transit had a fleet of natural gas busses, and the
maintenance costs totally killed the project.

The converted diesel engines were failing at a very high rate. Don't
know if it ws due to lubrication issues, valve issues, or what - but
the engines were apparently good for about 1/4 the normal life of a
diesel. The cyl heads are heavily modified and they need spark
ignition - all of which could have been involved in the failures.
And
the intitial conversion price is gawdawfull too!!!

Can't imagine how a natural gas conversion from diesel could be cost
effective.

L/A chose a different approach.

When it came time to rebuild and/or retire a diesel, it was replaced
with a natural gas engine.

Just one of the reasons it took over 10 years to accomplish.
