But, instead of heading straight into North Yard, the train came across Bypass 2 and will wait for its counterpart, the MNYGR, to depart before backing into the yard.

It lifts, lines, and tamps the track, as well as dynamically stabilizes the rails so that trains can safely run at track speed over the track. This is the final piece of equipment in the tie gang.

It moves from tie-to-tie...every tie, regardless if it is new or not...grabs the tie and shakes it to ensure the ballast falls properly under and around the ties. The long pole/extension in front of the tamper ensure that the rails are aligned and in gauge. Email Questions or Comments to the Webmaster or add a comment to the picture.

All of the ties you see that are perpendicular to the rails are new ties that are waiting to be installed beneath the rails.

A long line of machines, each with its own specific purpose, stretch west on the tracks west of Leyden. At the front of the line (closest to the camera) is a crane that is piling up old ties.

Maintenance workers are walking the rails and make sure old tie plates have been moved out of the way ahead of a crane that is piling up old ties.

A hundred feet or so behind the extractor, a crane is working to clean up the old ties. It is picking them up three or so at a time and putting them in piles along the right-of-way to be picked up by a work train in the future.

Work trains dropped off new ties along the right-of-way a few weeks ago. However, if a few extra ties are replaced, this crane has some new ties in tow that it can lay on the ground if they are needed.

Photo ID: 113310 Date Shot Photo By Thursday, November 13, 2025 Kevin Morgan Location Times Viewed Barbara's Gulch (MP 15.9 to MP 17.2) Arvada, CO 167 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) Union Pacific UP is in the midst of a major maintenance project on the Moffat. This particular piece of equipment is called a Tie Extractor/Inserter (TE/IE). A clamp on the side of the machine grabs onto a tie on the outside of the rail and pulls the tie out from under the rails. As you can see, not every tie along the rails is being replaced. The new ties are laying at (roughly) 45° angles to the rails. The old ties are perpendicular and will be picked up by the next piece of equipment.
