Artur~
Sorry for not posting pictures of my RD Slug yet, I have to wait for camera time. I am curious as to how you are going to route the wires between the units. I see that part of the receptacles are metallic, I assume that you will just run the cabling into the receptacles for power? Are you going to connect the mu hoses, air line, Etc ? My plan is to try and connect everything between the units, even the handrail chains.
Regards, PVRR2647

Regards, PVRR2647 yes i will run all the cabling, 4 of the cables will carry power for the motor and lights wile all the others will be empty wire jackets like you mentioned in a earlier post or black thread if it looks ok. the power connections will be small gauge wire with very short pins soldered on the ends so they can plug into the metal receptacles.

Artur~
What's the amperage draw for the two motors that you have? Do you have a decoder that will handle the load of both motors? I was thinking about running both of my motors off of one DSD. But I'm not sure that the Tsunami TSU AT1000 would handle both motors and the speaker for one unit, without the danger of overload. The other idea that I have is to run jump wires between the units from the truck pickup wires, so that the units will benefit from 16 wheel electrical pickup. There are more than enough cables/hoses between the prototypes to achieve this.
Sincerely, PVRR2647

Stephane~
I guess I'll have to break out the Fluke multi meter, too see if the DSD that I have in mind will handle the current draw from the motors in my models. I'm using Atlas Gold series GP40-2 phase 1s. I'll keep everyone that wants to know posted, when I get the results.

PVRR2647 Hi Stephane, the motor i'm using in the slug only draws 0.6A at max efficiency and I'll be using a genesis GP9 frame and motor so whatever that motor draws. I'll be using a 1.5A decoder that should be more than enough for both motors. here is data for the CD rom motor I'm using www.alibaba.com/product-detail/3V-24VDC-Micro-Motor-for-Electric_2006263989.html

artur If your GP9 is powered it's a B unit or calf. Slugs are nothing more than a frame w/ alot of added weight, traction motors, trucks, etc. They get their power from a "mother" (cow) loco. Rode slugs made from old 6 axle ALCOs pulled by SD39s alot in BNSF's Barstow yard as a conductor.

Andy, You are absolutely correct. 1:1 slugs have no prime mover. I have seen many slug models be powered for extra power when switching yards and still be called a slug by the builder. No foul here..... Cheers, Mike

No foul here..... Cheers, Mike I agree: slugs have no prime mover. But in the 1:87 scale, the only way to provide traction power is to actually put a motor inside, since the idea of that project is to add extra traction so I can shift a bigger amount of rolling stock in a yard. The benefit to have a decoder (but no sound of course!) and motor in the slug allows to use it with different "cows" or simply change it's position. If I can fit a decoder in too, I sure would prefer that option, even to the expense of not having operational ditch lights (due to the limited space). S.

that's the problem there really is not much room in there, N scale decoder and motor might be an option.

What about these? I imagine they would only work with blombergs, provided the wheel spacing was correct...

I'm not really sure I see the point of that other than doing it like the prototype. The big thing that differs from models and the real thing is electrical pickup: the prototypes get all their power from onboard the locos, but models have to pick it up through the tracks, and are subject to dirty track, dead spots, unpowered switch frogs, etc. Having pickups from the slug tied into the main power basically doubles your electrical pickups, making it less likely the whole setup would stall if the loco happens to go over some dirty track or an iffy switch, and operate more reliably overall.

Funny that you should post these truck assemblies, I asked the Kato rep at the Train Show in West Springfield this weekend when they (Kato) were going to make hood unit models using this setup. He said that it really isn't adaptable to hood units due to the space required for the truck to turn and that the bolster height is also to high. He lastly said that that is the number one question that Kato gets.

That's a really good idea I just wanted to make it as simple and as little wires as possible, with the lack of room under the shell I don't want anything getting tangled up in the drive shafts. Right now I will have a total of 4 wires, 2 for the motor and 2 for the forward direction head lights, no lights in the revers direction I don't see the point since its always going to be connected to the mother. also no decoder in the slug, this give room for more weight. keeping it simple and functional
