| In 2007, Colorado Railcar built track geometry car DOTX 220 for the Federal Railroad Administration. The car is based on the DMU/trailer platform, and differs from other cars built by CRM before or since. Most noteably, this is the first car built with the smaller roofline windows. It also features a full light package (headlight and ditch lights) on the B-end, though it doesn't have a control cab. DOTX 220 is equipped with a full suite of track geometry measurement and mapping systems, allowing it to take real time track geomertry, laser-measured gauge, profile and ride quality measurements and record the data in its own systems at extremely high speeds. The car has crew seating for up to 20 - 16 in the inspection gallery at the B-end and 4 in a technicians' station at mid-car. It is also equipped with a small galley, ample storage, and an ADA-compliant restroom. Length...85 feet, height...14 feet 7 inches...light weight...196,000 pounds.
