Metro Tunnel case study

CYP and large-scale tunnel asset capture

The Metro Tunnel handover involved more than 10,000 components, including trays, pumps, brackets, and structural items. Every item needed the right name, photo, and metadata.

Before digital capture, teams spent too much time fixing file names, sorting folders, and reworking incomplete records. Tunnel conditions made it harder because connectivity was inconsistent.

CYP used Trax as a field-first workflow:

• Offline capture underground, then sync when connected
• Asset records linked to location and metadata at point of capture
• Export bundles formatted to CYP naming and handover requirements

This changed where effort was spent. Engineers spent less time cleaning files and more time progressing work.

“We have documented over 10,000 assets so far. The biggest saving has been the admin we no longer do.”

The project also showed that onboarding matters. New crews were able to get productive quickly, which is essential on multi-contractor tunnel work.
