Dual motors

I intend to fit a decoder to my HO gauge DD40AX, this loco was claimed to be the largest diesel ever built and was run by Union Pacific, it pushed out 6000 HP using two separate engines.

In common with the prototype the model also has two motors each driving its own 8 wheel truck. Has anyone ever fitted a single decoder to run two motors and if so are there any special considerations regarding the amperage required?

I would like to fit a sound decoder but there is not enough room unless I cut away the part of the die cast split chassis which occupies the fuel tank space.

Yep, Microscale make a blistering array of UP decals but hetting the right ones
Well you'll just have to wade through them till you find them. Microscale make two types of decal setting solution "Micro Set" which is in a plastic bottle with blue writting is your basic solution. It'll prepare the surface for the decal, soften the decal and make it sit. You can use this one numerous times to get the decal down and bubble free. "Micro Sol" is the vicious one. Easily identified by it's red printing. You use it on irregular surfaces after you have used the other. This one really softens the deca, so much that if you brush it after applying it the decal will just wrinkle up and be ruined. So you brush it on after the decal is applied with the Micro Set and has dried, brush the Micro Sol on once then let it dry. So long as you let it dry before applying it again you'll have no problems. Oh and you'll need Armour Yellow, Harbour Mist Gray and Antique Silver to paint it with.

Got the decals from microscale in the USA, excellent service, recommended.

while we are on the subject. where can you get "microset" and "microsol" in the uk?

Peter, It's funny you should say that as the price of the kit down here is a lot less that it is up there. The big plus is that everything is supplied with it, motors, gearboxes and wheels. Motors are 1620 Mashimas, gearboxes are NWSL 36:1 single idlers and wheels are RP25 profile Romfords. Have a look on www.arkits.com.au
under Footplate Models. I think it's listed as A$595 which is about 245 UKpounds. It's not a hard kit to build just time consuming but well worth the effort. Send me your email and I'll send you some pictures of mine.
