Now where did I leave that leftover SD40 truck??? It's SUPERCRITTER!

[randgust]

Wow, this is just too cool for a critter.  Somehow I don't think it needs three traction motors, maybe one and a bicycle chain line like the 25-tonner:

80-tonner, 56,000 pounds of tractive effort???  375HP?   Hmmmm.  Of course, you don't need sophisticated wheel slip controls with a chain!

That looks really cool . Leave the unit unpowered so there is room for the engineer with see-through daylite . Then make 3 powered B units . Paint silver with a red cigar band .

'Hustler' brought to life?  Wonder if its over or under 40 miles an hour at six volts...

It doesn't look too difficult to make, considering Kato now includes the gear tower with the truck.

WOW!! Exactly what I'm looking for!!! I was gonna freelance something like this. I gotta take some pics,but I just built a power unit from a junk Bachmann Dash 8,[So,yeah,pretty much ALL B-Mann Dash 8's are perfect candidates..] would fit that perfectly!! The B-Mann truck is perfect for critters,the worm gear is part of the truck,and the tower is on the end,not in the middle.
   I pulled the worm off the shaft,the motor shaft goes right in the tower,presses through the worm.You need to press a small piece of shaft in the other end of the worm.The biggest job is gluing and wiring the pickups in,since the chassis doesn't hold it in anymore.I built one for a boxcab I'm building,uses the Dash 8 motor,too..I was gonna post pics when it was done..

Back 'in the day' the Roco E-7 had a six-axle truck with the fixed gear tower at one end.

What others were ever like that?  Do you have a picture of the Bachmann one?   Is there any 'SD40' truck out there like that?

That's what you need to make this work.  There's several small 3.5v gearhead motors that would interface with that, and keep the speed within limits, but the drive has to be on one end for room.

I suppose you could try with an old Roco one..yeesh

[LV LOU]

Randy,I'll get a pic tonight,but the entire motor from the dash 8 will fit on top of the truck.The tower is all the way on the end..I just looked at the B-Mann parts page,it's the old Dash 8 that has the right truck.

[randgust]

Why would this get moved over to the crew lounge when we're discussing how to do it in N scale?   I saw this happen in trainboard so I posted it here, thinking it would stay where I wanted it... thread will now drift off and die.

[tom mann]

I think Ian thought it was going to be otherwise...I'll move it back.

[wm3798]

Itchy finger Ian.  Good thing there's lots of paperwork to do when a cop shoots someone... probably the only thing that spares the miscreants of Ossipee.

Besides several Bachmann locos (older and newer), IIRC, con Cor / Roco RDCs has a worm integrated with the truck.

Also one of the older releases of Bachmann DDA40X had its motor as a part of the truck assembly (self-contained power truck).  That was the one where the rear truck was a dummy.

Kato RDC and NW2 trucks also have worms integrated in them.

Take this, replace driveshaft with small motor, attach body, job done.
