Greetings from the Walla Walla Valley!

I have an Etsy shop and do online research to find information for my listings, but Bachmann seems to be one of the more difficult brands to get information on.

Is there an online database where I can research Bachmann trains? I typically try to give accurate information on date of production, as well as a few loco/car details.

If not, I am hoping someone can assist with the production years for the following:

HO Bachmann Spectrum GP30 Diesel UP #731 (Item No. 82010) in yellow/gray.

I am a new user, so any useful tips with the forum will be appreciated.

Thank you, in advance & have a nice weekend.
