The original wooden sleepers of Mail Rail need constant care so they can continue to carry thousands of visitors a year through Mail Rail’s tunnels.

Make your mark in the tunnel and your company will enjoy exclusive benefits whilst helping us care for this marvel of engineering, so it can be enjoyed by future generations.

Benefits to your company

By supporting a sleeper your company will receive the following:  

Engraved plaque on a dedicated Mail Rail sleeper for two years (with an option to renew).

Private Tunnel Walk for up to 24 guests to view your company’s plaque and explore Mail Rail’s network of tunnels on foot with an expert guide. This could be a unique event for your employees, or an engagement experience for your clients.  

Options to enhance your Tunnel Walk event with catering add-ons and use of our award-winning event spaces.
