Jackson Model 4000 Track Tamper

The Jackson Model 4000 On-Off Track Tamper is one of only a relatively few units built between 1968 and 1972. These start with serial number 117855 and end at 117860, so there were not very many of them produced. This particular unit was factory converted to operate on 36" gauge track, making it even more obscure.

The scope of our project is to return this unit to operating status. To do so, we are currently rebuilding the 2-53 Detroit diesel power plant, the three phase electric generator that powers the vibratory work head motors, the brake system, the hydraulic system and more.

As of September 2012, the unit has been completely re-wired, and all of the brake cylinders have been replaced, among other things. Jackson was taken over by, and is now part of, Harsco Track Technologies. We've been working with their parts department, who have been very helpful with information and even some parts from inventory.

This is how the unit looked when restoration began in April 2011:

June 2011. Degreasing was done the slow, hard way—by hand:

September 2012. Engine and generator have been removed for rebuilding:
