Smarter Tram Washing with Digital Innovation

Digital engineering meets clean mobility

Innovative, efficient, and future-ready

To meet Zurich’s demand for a high-performance tram washing system, BHB Waschanlagen Vertriebs GmbH partnered with ATINA and Mitsubishi Electric to deliver a smart, sustainable solution. By combining cutting-edge automation, low-code programming, and a digital twin, they drastically reduced development time while achieving top-tier cleaning results. This project is a showcase of how digital transformation empowers even small manufacturers to lead in innovation.

Challenge: Efficient cleaning for a busy city

Zurich’s public transport needed a fast, energy-efficient tram washing system with top-tier cleaning results. BHB, a small German manufacturer, had to meet high demands while keeping development and commissioning time low.

Solution: Innovation without complexity

Together with ATINA and Mitsubishi Electric, BHB delivered a cutting-edge system using:

Low-code programming for faster, error-free development
A Digital Twin for virtual testing and rapid commissioning
Modern automation with Mitsubishi Electric’s FX5U controller and FR-E800 inverters

Result: Quick setup, consistent results

Commissioning time cut to just a few days
80% less code, easier maintenance
High cleaning quality with reduced energy and water use

Why it matters

This project shows how digital tools and strong partnerships empower even small manufacturers to deliver smart, sustainable solutions—faster and better.
