The cab is equipped for dual-mode control, allowing the operator to steer via road tires or engage rail wheels for track work.

The 4000TM sits in a sweet spot of the Trackmobile lineup: heavy enough to pull four to six fully loaded railcars (up to 4,000 tons on level track), yet agile enough to drive over grade crossings and road surfaces. Unlike a traditional locomotive, the 4000TM uses steel wheels for rail travel and a set of retractable rubber road tires for highway mobility. Switching between modes requires precise, sequential action—exactly the kind of operation where a manual isn’t a suggestion; it’s a lifeline.
