N Scale GP-40 diesel locomotive included in Thunder Valley set

[ACDC]

I purchased a N Scale Thunder Valley set last year.  Since then, I have built a 60" x 30" layout with an elevated figure 8 section with a bridge and two turnouts.  There isn't any information about the the GP-40 diesel locomotive that came with the set nor is any available on the Bachmann web site.  On the undercarriage there is a cover with two small screws and what appears to be a serial number:  K190417.  Is this loco DCC ready? Or does something else fit under this cover

Hi ACDC,

The GP40 locomotives that come in our N scale sets were not designed to be DCC Ready. You may still be able to fit a decoder inside the body shell, but it will be a tight fit and they do not have a plug receptacle.

Does the cover on the underbody (the fuel tank) you mention have holes in it? If it does, you have our redesigned GP40 and that space is the speaker enclosure. You can place a speaker in the fuel tank if you do a sound decoder installation (and our DCC Sound Value GP40 already is equipped with one.) If there are no holes, you have an older version of the GP40 that is not DCC compatible.

Also, we do have the same redesigned GP40 available in separate sale, you can refer to this listing for more information.
