• Perform fault-finding, diagnostics, and repairs.
• Complete scheduled servicing and preventative maintenance.
• Assist with heavy overhaul repairs (C1 / C4)
• Overhaul and test still boilers.
• Service catering and gas equipment.
• Support depot infrastructure repairs when required.
• Maintain a safe, tidy, and compliant work environment.
• Liaise with depot teams, contractors, and wider engineering staff.

• Complete high-quality repairs and component replacements.
• Ensure full compliance with railway safety regulations and procedures.
• Provide cover at additional sites when required.
• Accurately document all maintenance and repair activities.
