.... THIS!
Specially designed for Nn1 discriminating railroads, when nothing else will fit.

On theone hand they do look odd, on the other hand, they are perfect for coal docks and the like.

"Remarks & Notes
These little machines are Field Pushers and Pig Pushers. Operated by longshoremen, they move on a narrow gauge track adjacent to the rail yard tracks. These machines are used to move loaded coal cars , two at a time, from the "buck yard" to the barney pit where the cars are then pushed up an incline to the rotary car dumper."

I wish I could answer you on that but I haven't been able to find out any more about it. I just think it has a sweet rugged look that the other pusher locomotives I've seen dont have.

Hi all,
now for today's dumb question - assuming these units had arms that pushed on the end of the car to get it rolling, how did you stop the car when you had moved it enough? It looks like the arms do not mate up with the car's couplings and there does not appear to be air pipes/hoses for the airbrake systems. Did you rely on a shunter on the ground winding on the handbrake or something else?
If these were used around piers and wharfs, one wrong move stopping a car in time and its "SPLASH" at the end of the pier.
TRUE story - the Habourmaster (aka port boss or Chief Harbour Pilot) was down at the one of the wharves at a local port. While he was there he saw a shunting "accident" where one of the wagons went off the end of the wharf after being given too much of a "nudge" by the loco.
So the Harbourmaster organised for a diver to go down and hook cables onto the wagon so that the offending wagon could be lifted back onto the wharf by the wharf crane so that the drowned wagon wouldn't interfere with port operations near the end of the wharf. After a period underwater the diver surfaced, without hooking up the wagon. After they got his helmet off the harbourmaster asked the diver if he found the wagon and why hadn't he hooked up the cables. In typical laid back Aussie style, the diver said 'Yeah, but you didn't tell me which B****y wagon you wanted - there's another 6 of 'em down there".
The names of the port and the wharf have been omitted to protect the guilty.

Here's a video of a Hulett unloader working. At around 1:17 you'll see one of these "mules" (?) move. I'm wondering if there isn't some kind of power supplied between it's tracks.

I remember seeing drawings for a poling car WAY back in he past, probably MR. Jose.

Those are great, Bernd. I'd still like to see some more of these in action. Did you notice the PRR #7 has a completely different arm design than the others? It looks to have a shock absorbing spring on it and I'll bet you are right. The arm goes in between two cars, thereby providing the movement power and the stopping power.

This link I stumbled upon while researching the pusher locomotive subject. I haven't looked through it all but I didn't find what I was looking for.
What I did find, however is about a bazillion nice old railroad pictures. Have a look!

Mike,
I collected quite a few of the pics from the first two links mentioned. A close look shows that they all had large springs on those arms. Nice find on that last link you posted.
Jose,
MR had that article. I've got it but don't know the year.

You ask a good question here Mike. After studying that pictured you linked to I can only come up with one answer. I think they are so long because of where the shoe is located, right behind the rear wheel. This puts the fulcrum point from the wheel to the shoe. So I'm speculating here that if it had a short wheel base it could possibly pull a "wheelie". But, looking at all the others it seems they all have the shoes near the cab. Why?, possibility for better visibility? Why not put the cab in the center? Seems like more questions arise than can get answered.
I came up with another idea of how they might have moved. Could there have been two cables in that center portion of the rails they ride on that I showed in that one picture. Kind of like the cable cars in San Francisco. One cable for forward, one cable for backwards?

I'm sure the arm is where it is for visibility purposes. I would tend to agree that the arm and he cab should be in the middle but none of them are made that way so obviously WE are missing something from the equation.
Again, it would be nice to read up on how these were used.... Other than just to say they shunted cars, that is.
I think at some point, I'd like to scratch build a PRR #7. What gauge do you think it is?

Here's a 12 minuet video. It shows them actually moving cars.

It looks to me like it could be 2' gauge. I've also come to the conclusion they were electric powered. They must pick up the current between the tracks.
I'm thinking of building a warf unloading diorama featuring a couple of the Hulett un-loaders. I just recently ordered a Walthers kit and have prints coming for the Hulett un-loader from Bearco Marine Models. They also have HO scale boat kits. I'd like to make it all animated. Tall order I know.
