Frankly, I'm sorry I ever started this thread.
OK, some more options:
A dynamic tamper?
A UNIMAT tamper?
A DYNACAT tamper?
The APT 600 rail welder?
The HTT Rail Renewal System?
The HTT Track Stabilizer?
The HTT Stoneblower?
Are any of these even remotely close?
Most of those are larger/longer than the unit we saw. Maybe part was missing. Unfortunately, my descriptive skills are not up to the level needed.
Riverotter, those pictures look like models!

Bummer, are you sure, it matches thr two arms thing.
I have a new theory. You were abducted by aliens and the machine you desribe is not railroad related at all, and is now millions of gallaxys away. Your love of trains just allowd you to remember the large piece of machinery.
Since my cellphone camera "remembered" it the same way I did - yes, I'm sure. From what I have found at the company site, the "two arms thing" seems to be a common design factor in some of their equipment.
Did you find a similar piece of equipment at the companys website you could link to here?
Worth the wait. What the heck is that thing? Do you remember what it said on the front?
