Dymax Rail Rider X2 – Track Excavator Hi-Rail Attachment

WHERE THE NON-MODIFIED EXCAVATORS RIDE

The real question was never, “Do you need a hi-rail excavator?”

It was always:

“Do you need a dedicated machine — or do you just need hi-rail access?”

The Dymax Rail Rider X2 is the answer.

A fully detachable hi-rail system that converts new or existing excavators for rail use — and converts them back when the job is done.

Installs in days, then it’s … ride-away.

No cutting. No chopping. No compromise.

How the X2 Attaches — Without Modifying Your Machine

  • Wedge-locking adapters (patent-pending) create a secure connection between the X2 undercarriage and the machine.
  • The excavator sits fully supported on the X2 structure—not cantilevered off the ends of the frame—for improved stability, safety, and machine support.
  • Modular front and rear railgear assemblies remove for off-track work.
  • Pre-hosed hi-rail system designed for simplified dealer or in-shop installation.

CONTINUED ROI

A permanently-modified excavator is a depreciating asset. At the end of its lifecycle, the only person who wants it is another rail contractor.

You invested nearly 7-figures in that machine. The next owner didn’t — and now they’re bidding against you.

Are you sick of funding your own competition?

The Dymax Rail Rider X2 is different.

Keep the X2 railgear. Sell the excavator. Re-invest the savings.
