The Strangest Ho Locomotive I've Ever Seen - 1980s Bachmann DD40AX W/Sound

[@davidztog9011]

Who knows how long it was in the box, Harrison. I'm sure you will need to change oil and grease. Wheels probably have that patina build up from sitting. Now you're gonna have to change a piece of track so the horn works. A new 9 volt battery and fresh AAAs may make a difference with the sound as you really don't know how much voltage you were providing with the Tyco transformer. I'm sure it made kids' eyes pop back in the day. Thanks for sharing. 👍 👍 👍

I have one I bought in the late 70's, it's put away with 400 engines and cars, my father had a huge HO model RR, when he died my brothers and I divided up his collection. Most of what we have are from the 70's, I haven't touched them since he died in 1983. My grandsons will inherit my collection.

[@SMTMainline]

It's nice to hear your grandsons will inherit them someday. I got into the hobby when my dad showed me his collection back in 2006 and I asked for a train set that Christmas which I was able to run his old locomotives on. It's a great hobby that unfortunately not many youngsters get to experience these days.

Man, UP has got the strongest, single frame locomotives for both steam and D.E. under its belt. Crazy to think

[@Panzer-535]

diesels maybe, not steam. there are other roads that claim most powerful rigid frame locomotives. example, the Western Maryland had the heaviest and most powerful Decapods (I-2) and were among the heaviest Consolidations (H8/H9)

I would still have it today if the basement had not flooded and destroyed my hard work. I got a paper route at 12 to be able to build that set. I think about it a lot.

I had purchased the model you have. The DD40X in 1987. However it didn't have the speaker sound , batteries & the controller. I have the updated models as well they're pretty well.. very genius with the substitute when the 9 volt failed to work. I was 100% impressed. Loved the video..☺🚥

[@georgiahex7387]

I believe it was 1984 when I received the Bachmann Centennial train set. It was the first train for my layout, 4x8. I had to go to my library to confirm the DD40x was a real engine. I have never seen a DD40X in person. It is my favorite engine after the F7 and F9. I prefer Bachmann for as a teen, and due to limited hobbies stores in my area, I found that Bachmann served me better than Tyco. My DD40X from childhood is long gone so I assembled a replacement set and, bought another DD40X engine while I was in the hospital, it was a panic buy . I enjoy your videos. Keep going with them

[@jlwii2000]

Nice layout!

[@ZakWolf]

Pretty interesting! I'm kind of reminded of how in the 60s Lionel had an HO-scale Santa Fe A-B-A diesel locomotive set that also used a battery-powered horn. Though of course Bachmann could pull it off with the DD40AX due to its' large body, just like how decades later the DD40AX would become Bachmann's first sound-equipped DCC locomotive. (A lot of older Bachmann products from the 70s and 80s are still being made today, in many cases as new and improved versions, like the aforementioned DD40AX.)

I use one of those TYCO controllers on my current HO-scale layout for powering the track turnouts, mechanical operating accessories and a few nearby lights. But to run my trains I use a Bachmann E-Z Command DCC system. It's kind of funny how back in the 70s and early-to-mid 80s, TYCO was Bachmann's biggest rival.

[@manthony1956]

This was forty years ago. As someone who has been at it for over fifty years, I can't say they were great runners. You can upgrade the pancake motors, but most entry level HO locomotives used some cheap motor. I personally prefer the earlier single motor all wheel drive Bachmann locos. Very noisy drive trains, but they pulled. Many locos of that era still had a single powered truck. And I remember my first flywheel loco. It was an Atlas GP-38, about 1975. With a skew wound five pole motor. This is about the same time Athearn change to flywheels. But my earliest locos had three pole Pittman motors with rubber band drive. It smoothed out the pulses because few locos ran well at low speeds, and whoa be to those who ran pulse dc. We've come a long ways, baby!

I have this locomotive, and it actually has 2 motors in it to give it 2 truck pulling power. Also, the battery holder is designed for 2 “AA” batteries, not “AAA” batteries. If you like oddball Bachmann locomotives, you should look up a 2-10-4 Texas Chugger by Bachmann. I bought this steam locomotive back in 1979, and it has “Electronic Chugging Sounds” that come out of the tender. The tender has a plug you plug into the the rear of the locomotive to receive its power. No push button controller required. Both of my locomotives still run after all of these years, and still provide their electronic sounds.
