Atlas GP40-2 loco insides
Posted by richg1998 on Tuesday, August 24, 2010 10:09 PM

I recently opened up this HO scale new loco as I have seen a couple forum questions about
the insides somewhere. It has QSI sound.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.

 Thanks for the pics Rich.  I have two of these beasts and I'm sure the info will come in handy later.

The shell comes off pretty easy. Just remove the coupler pockets and the shell wiggles off with a little patience.

Yeah, I found the shell slips off rather easily.

 Not much room for weight. How does it pull?

I will have to wait until I get to the club layout as my home layout is not very large.

Couple more photos.

 Not much weight? The front decoder mounts looks like heavy metal, and it has a shelf all the way out to the short hood, over the front truck. The speaker mount is also solid heavy metal, and it looks like there's more weight behind it, out to the end of the long hood. I suspect it's plenty heavy. I know the Trainmaster with the same decoder/speaker arrangement was a beast.,

The weight is good for a 4 axle loco.  They pull great.  I have 4 of them.

I have a small digital scale that goes to 12 oz max. This loco weighs a little more than 12 oz as the scale is maxed out.

Still lighter than my PCM F3's and BLI F7's that weigh in about 1.2 lbs each.

I read an article that said they weight 12.9 ounces.  Not bad for a small loco.

From what I see in one of the diagrams I posted, the DCC ready version must weigh a little more than the sound equipped. There are two weights to be removed from the weights used to hold the speakers.

I would have never thought of installing speakers the way Atlas does. By the way, the speakers are in series which each other if you did not look closely at the photos I took.

What's the trick to remove the trucks for greasing?

I have not gone down that path yet. I will look into it after this weekend.
