Steam & Excursion > Memory loss

Help an old man out here.   I was trying to remember what was involved in steam locomotive classified repairs and can't remember what was involved in class 1 through class 5.   Don't recall whether 1 or 5 is the most involved.
It's hell to get old and forgetful.

Don,

Isn't that stuff covered in a Locomotive Cyclopedia? I'll go upstairs tomorrow and look.

That gets asked, wasn't 4 boiler and 5 everything but the hoghead's armrest?

Out

Here is what I have, but it is a little old.

Thanks guys,

I should have dug out my Cyc.   I used to know that but for the life of me couldn't remember enough of it to matter.

I remember all of that. I think. What was it that I remembered ?   :) :)
