From the CDOT website about the status of the Independent Wheel Truing (IWT) Facility:
Project Description:
This Independent Wheel Truing (IWT) facility is for re-profiling the steel wheels on the new and
existing New Haven Line and Shore Line East rolling stock. This re-profiling consists of milling the
wheels to restore wheel diameter parity and profile as a result of the stresses of track wear, drift,
spalling and wheel flat spots. The wheel machine is an under-floor tandem type machine which can
true both axles on a truck at the same time as vehicles are pulled over the machine for ease of
operation and to speed turnaround time. The building encloses the machine pit on a single track and
includes extensions to house a pair of cars indoors at both ends of the facility.
