Was at a show two weeks ago, PNR...
A guy had a Mint Pennsy Athearn F-7... It had a single power truck. The guy claims that he's looked in the Athearn collectors book and that locomotive is nowhere to be found.
He thought that it was an error build... I checked it and noticed there was no kit-bashing...
I should have taken a picture, since it was also labled on the box "Athearn Single Drive... F-7 Pennsylvania"
He had another similar Pennsy, mint boxed, labelled ... "Dual-Drive..." Very unique to my eyes!
Anybody else know about these? John

Is that a power-trip or just another pick-up line?

Somehow, just recently I recall selling an Athearn F7 diesel locomotive with a single rear powered truck and a standard dummy truck in the front. It was the old geared drive/pre-flywheel design.
I tried, but had no luck finding the prior listing or anything in my email.

I've seen and heard of these. Rare find. Athearn didn't make the drive. IT'S MADE by separate company.

| Lionel and Athern had simular ones. A rubber tube connect the drive gear in the truck to a motor. Lionel used a Pitmon motor simular to that of the Mantua steamers.

What was it, a rubber band drive with just one shaft?
It's possible early gear drive locos had one gear truck, but it seems unlikely.
Athearn revised a lot of stuff in the 60s though - look how many variants of the Pacific - so anything is possible. I have an SD45 I picked up cheap that had been dropped, and I take it apart and the motor is white plastic instead of black, the frame takes the metal coupler covers and the fuel tank profile is even a tad different. The handrails on it were the first type where the top of the stanchion was pressed and a hole punched for the main rail. too. I didn't know they made any like that until I found this one.

yes Athearn sold them in the very first gear drives. If it was correct it should have had cast gear towers with plastic or brass gears incased with plastic side frames pressed on. If you search the forums you will find pictures of them and can compare, they are on the rare side but not uncommon to find one or two at a train show. Most people do not know what they are and put them in a parts box.
The biggest problem I have had with them when repairing the wheel sets they come out of quarter(?I think that is the word I am looking for) because the wheels are installed on plastic inserts that crack. I have found that superglue is the best fix for them to be repaired.

Have never seen one in person, either they were sold more in one particular region or they're more rare than you think.
Most Athearn gear drive stuff that predates the black motor with two dark cast flywheels and post-dates the HI-F drive is not particularly common.

Look up Athearn Dual-Geared Geeps.
http://www.hoseeker.com/assemblyexplosionAthearn/athearngp9dualgeared1957pg1.jpg
Some folks claim they were Olympic somethingorother, or that Olympic made them later, or that they are Japan in nature.
They were the early Gear drives, I was told that Athearn found them to be too costly to make and compete, so they went to snap-together plastic drives.
They are very smooth and quiet, especially as compared to the plastic ones.
If Japanese, they would most likely have had metric screws, but they are 2-56, as the drawings show.
Just an opinion.
I have a spare set of power trucks, too.

Thank you, people.
"Should have bought 'em..."
well, I've done enough "shouldin" on myself that I am happy just enough to have seen it and upon reading your comments am quite satisfied that I told you about them.
Forge ahead!
