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.

Ive found yet another of PRR #7. It's an Atlas Car Company Dockside car pusher according to this website.

Some day, I'll have to visit that museum where it's on display.

Here is a similar one.

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.

Bernd

Just wondering.... Why do you think some of these things were so long?

Case in point. http://www.northeast.railfan.net/images/prr_atlas2a.jpg

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?

Bernd

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.

http://www.youtube.com/watch?v=JErREoMOdDc

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.

Bernd
