Harsco Track Technologies (formerly Pandrol Jackson) Electro-graphic Tamper ET-17 in Talkeetna (June 2000)
Additional commentary by Tom hatfield, "Model 3300 Tamper. What we nickname a chase tamper. It follows the Model 6700 Tamper, photo JC-et-18 for increased productivity. It can also work alone. This one in the photo does not have the capability to line or level track. I believe it can be outfitted with the necessary equipment."The basic purpose of an electro-graphic tamper is to align the track both in elevation and curvature. Travel speed is a 15 mph on a 2% grade, 28 mph on a 1% grade and a maximum speed of 40 mph.
