Well since we can no longer reply to topics after 120 days, I guess we just have to duplicate them now.

 

In the previous thread I showed swapping the FP7's from the claw to Kadees, and pulling them closer together. I finally got some pictures of the 2 rail pilots that I swapped out to get rid of the huge hole in the front.

 

 Here's the claw with the 3 rail pilot.

Kadee and the 2 rail pilot. I also added the air hose.

On the lead unit, I pushed the Kadee back further for a better look since it's the one you see head on.

On the trailing unit, I left the Kadee out just a bit further to allow room for the trip pin on the 1st car so it don't hit the pilot and derail in the curves. (Scratch built caboose by Brother Love &nbsp

You can see the trailing unit's coupler sticks out further when it's not hooked to a train. When it pulls a train, you don't even notice that small difference.

The only thing I would still like to do is body mount the steps. I think they are in the works for the F7's... (I hope so) I also hope the drive train on the F7's are the same as these FP7's because they are unbelievably smooth and quiet. They don't fight each other, even with the B unit being non powered.

After emailing Scott the unpowered units proved to be a drag, pun intended, but if you don't buy the engine offered, or cars.  You won't get them and 3rd rail so far ain't reissued JACK1!!! if you don't buy it when it's produced You lose. I think I sat on the fence one too many times, Now.. I have to pay a premium if I want something bad.. Just Sayin

Pictures of the F7s and FP7s show 4 MU Hoses.

And 4 hoses per side are correct for first generation units such as F-units, GP7, GP9, because they used a pair of hoses to m-u the sanders.  So the research was correct.

 

Second generation units normally omit the outer hose on each side, as the standard for m-u operation of sanders changed to electric, using the jumper cable between each pair of units.  However some roads still kept the outer hoses by special order to allow newer units to m-u with older ones.  Most railroads just changed the sand control on older units to electric and never had the sander control m-u hoses on their second generation units.  (Or, as in the case of Santa Fe, did not m-u first and second generation units.)
