On a high-speed rail project, technicians and machinists are needed to inspect, repair, and maintain rails and equipment. Some technician roles have titles like track equipment operator or heavy equipment operator, and in these jobs, you service equipment and perform repairs and maintenance on mechanical, electrical, and hydraulic parts. You also document the status of projects. Alternately, you can work as a laborer, installing and repairing train tracks, road crossings, and signage. If you have appropriate qualifications, you can work as a machinist. In this job, your duties and responsibilities involve using blueprints and drawings to fabricate metal parts on a mill or lathe.
