Rolling stock designation

Evening,

Curious question. Is there a listing of rolling stock designations?
Probably a better way to ask that, but not sure how to word it.

Thanks Jason

I could not think of the AAR term.

That's definately the best list as it shows changes to the types over the years.

These codes are the AAR's "Mechanical Designation"; there are modern car type codes which are a letter followed by 3 digits. Which are more detailed, but you need a detailed lookup table to figure them out, and they're used in registers but not painted on cars themselves.

Am I correct in reading the dates as start and stop dates of the designation's use and, where there's only one date, that would be a start date and the designation's still in use?

What's up with those MOW descriptions that have no designation?
Now seeking Pacific NW N scalers to create a Modutrak-style modular club featuring NP's shared mainline between Seattle and Portland. PM me if interested.

The dates show which issues of the ORER the description is pulled from. Looks like the highest one used there is 1999, so if it's to "4/1999" that's basically to present.

Non-interchange and MOW equipment isn't listed in ORERs; there are some standard designations but also lots of custom types of work equipment. Not sure why those particular descriptions without designations were specifically listed in the source ORERs.

I appreciate the response Chris, but I didn't get an answer to my first question from what you wrote. I'm a bit dim witted. From your response I would say, yes, the dates are start and stop, but maybe you could clarify for me?

I don't believe those dates are specific to when the change happened.  The list is compiled from a number of ORERs over time.

But it's when the list compiler first noticed the changes, right? (Sorry for being persnickety.)

Right.  You'll notice all the change over years correlate to the above ORERs.

No worries, that's what people without layouts do.  :)

If a single date is listed, that's the only ORER that referenced that particular description.
