Maintenance Services
Comprehensive technical support for ticketing infrastructure
Each service is designed to address specific operational challenges faced by London Underground ticket vending machines. Pricing reflects the technical complexity and time requirements for proper execution.
Routine Maintenance & Inspection
Comprehensive assessment of all critical components including coin validators, note acceptors, card readers, thermal printers, and touchscreen interfaces. We inspect mechanical wear, clean sensitive optical components, and verify calibration accuracy.
This service includes testing of all payment acceptance methods, validation of receipt printing quality, and verification of cash dispensing mechanisms. We also check software version currency and assess whether firmware updates are recommended.
Emergency Repair Service
Immediate response for critical system failures affecting passenger services. Our technicians carry diagnostic equipment and common replacement components to resolve most issues during the initial visit.
This service prioritises rapid restoration of basic functionality, with follow-up visits scheduled for any repairs requiring specialised parts or extended downtime. Available during operational hours with callout response times averaging under 45 minutes within central London.
Software Updates & Calibration
Installation of manufacturer-approved firmware updates that address security vulnerabilities, improve payment processing speed, and add support for new fare structures or payment methods.
Calibration procedures ensure accurate fare calculation, correct change dispensing, and proper card read distances. We verify all updates through comprehensive testing before returning the machine to service.
Component Replacement
Installation of genuine manufacturer components including thermal print heads, touchscreen assemblies, card reader modules, coin validators, and note acceptors. All replacement parts come with manufacturer warranties and include calibration.
We maintain inventory of high-failure components to minimise downtime. Replaced components are assessed to determine failure causes, providing insights for preventive maintenance scheduling.
Preventive Diagnostic Testing
Advanced testing using specialised diagnostic equipment to identify components showing early wear indicators. This service detects issues before they cause operational failures, allowing scheduled replacement during planned maintenance windows.
Testing includes thermal imaging of electronic components, electrical continuity verification, mechanical wear measurement, and transaction simulation under various load conditions. Results include detailed reports with recommended action timelines.
Annual Service Contract
Comprehensive yearly coverage providing scheduled quarterly maintenance visits, unlimited emergency callouts, priority response times, and all replacement parts at no additional cost. Contract includes dedicated technical support contact for troubleshooting assistance.
This option delivers significant cost savings for stations with high machine usage or those experiencing frequent component failures. Scheduled maintenance prevents most emergency situations while ensuring continuous operational readiness.
Service delivery process
All services begin with initial diagnostic assessment to confirm the scope of work required. For emergency repairs, this assessment occurs on-site. For scheduled maintenance, we coordinate timing to minimise impact on passenger services.
Upon completion, we provide detailed service reports documenting all work performed, components replaced, and any recommendations for future attention. These reports assist transport operators in budget planning and maintenance scheduling.
Emergency services receive priority scheduling with guaranteed response commitments. Routine maintenance can be scheduled during off-peak hours or coordinated with station-specific requirements.
