Would someone please advise what this part is? I asked this same questions days ago and one got one reply that lead me to the part number location but not a description of what the part is. Thanks again for your time.

Its a motor driver. What is surprising is its listed as available. All the TMCC and first generation Legacy motor drivers have been declared obsolete.

What engine was this used on?
I'm not familiar with the "EM2" on the tag.

There is no reverse lookup. You would have check every engine that came with Odyssey or Odyssey II. Actually this is the first I have seen a DCDRS board. They are either DCDR (w/o cruise) or DCDS (with cruise).

Thanks for the replies. I stumbled on the part while on Lionel's sight and as Norton said the DCDRS coding threw me off. Thanks again everyone.
Looks like it was used in the D&H Alco PA-1.

I too am surprised it's listed as available. 
Gunrunner, would you know if this is an Odyssey driver board?
Thanks, Mike

Thanks, Mike
If you check the link that John posted, notice the motor has a magnet and tach sensor. Plus the board is identical to all the other DCDS boards. Pretty safe bet this is an Odyssey Cruise board though hard to tell what generation, lurch or post lurch.

@Harbor when I first saw your original Topic Lione Part Information, I became curious at to what type of board the DCDRS is. After trying many different types of searches, the only resource I found discussing this actual board is this Jan 2003 post from @ben10ben on another forum.
According to that post: Lionel released the DCDRS Odyssey Board in 2001 as a replacement for the DCDR. Link to that Article here> Classic Toy Trains - TMCC late updated?
I don't know how accurate that statement is in every way it could be interpreted. Ie. not sure whether it can be substituted as a direct replacement for a DCDR without modifications.
Thanks fellows, I really appreciate you taking the time to provide the information.
@Harbor You're welcome of course. Out of curiosity, why are you wanting to know if the DCDRS is an Odyssey1 board?
No problem, I would like to purchase as a back-up. I have a few TMCC Diesel locomotives and wanted a spare in the parts bin.
Since it's unclear at this time whether this would be a direct replacement, you may want to consider the improved Cruise Commander M from 3rd Rail - The Electric RR Co.
Point taken, thank you.

On sale its 100 bucks cheaper. Reason enough to consider it as a backup.

Pete, that's definitely a good point. I realized that the DCDRS is cheaper, but if it has the lurching issue, or doesn't work as a direct replacement for the DCDR... I guess the choice depends on one's point of view/risk tolerance. Personally, I would rather spend $150 on something I believe will work well, vs. spending $50 on something that may have issues.

No idea of Mike’s risk tolerance is. I am more of a go fast, take chances guy. Even the lurchers run. Its really only at startup or when lashed up is there an issue.

It's a DCDS Odyssey I board, it is NOT a direct replacement for the plain DCDR non-cruise board. In order to use this board, you need an Odyssey I speed sensor on the motor with the magnet ring on the flywheel. This is the one used in that particular locomotive, but any Odyssey I speed sensor that you can align with the flywheel sensor properly would work.
The one above is $40, this seems to be a much more economical price at $12. I think the $40 one was designed so it could be oriented in two ways on the motor, but that's usually not needed.
