Lionel Chessie system B&O diesel 3849

can someone give me a stock number for this engine I went to lionel.com and tried to look it up in my pocket guide can’t find it it does say on the side built by lionel 2001 I’m wondering if this may have been some type of special issue engine. I’m adding a couple of pics so you can see the engine. its dual motor

“New York Central Flyer Freight Set” in the 2001 catalog shows a set with this engine.

Vol 1

Thanks for your help it stated this

"Detailed molded GP-38 diesel locomotive with dual precision can motors, transformer controlled forward, neutral and reverse, stamped metal frame, operating headlight, diesel horn and molded trucks "

i still would like to know what the engines stock number is (6- xxxxx) oh well maybe maybe never know lol

RT, Chessie Diesel Freight Set 6-31915. Hope that helps.
