How is Acela II testing going? I heard rumors it's not been going too well and the punchlist is getting rather long.

Don't know, but at least it can go 165 mph...

Wouldn't surprise me if there is a long punch list.  Even when buying "standard" locomotives from EMD and GE, the punchlist often was quite long.

Neat!  What is a punch list?

What is a punch list?

It's a contractor's term: a written list of 'items for attention' or things that need to be remediated or fixed.  It was so called because practice was to use a physical punch, like a ticket punch, to confirm that each item was responsibly done -- in some organizations, distinctive punch shapes were assigned to particular people so the person responsible for a particular item could be identified.

There are always a ton of things, big and small, where the product doesn't meet the spec.  Sometimes, it's a matter of how the purchaser and builder read and interpret the spec.  Sometimes, it's an actual blunder.

A key point being, whatever it is, put it in the list with a punch box next to it.

The alternative to 'not documented, not done' sometimes involves noting what are routine or boring things, or details seemingly beneath notice.  Better to note them when you're responsible, or make yourself responsible, for the quality of the 'product'...

On the other hand, there's the wisdom inherent in "never volunteer information" ... which might happen with the, ahem, wrong items, or wrong wording, on the punch.  As with most things, there's common sense involved.

punch lists used on construction a lot.  Have several hundred items on utility construction anything from wroong drain grates to "as builts" not correct. Airplanes missing screws to various labels, etc.
