However, the market has contracted significantly over the past decades, reflecting longstanding structural challenges in service design and passenger experience. The company aims to address these challenges by rethinking overnight rail. Unlike traditional night trains, where passengers share compartments, it is developing trains that provide each traveller with a fully private space.

The concept combines transportation and accommodation into a single overnight journey at a comparable price point, with departures from city centres in the evening and arrivals the following morning. Its approach is based on a modular, high-density cabin system integrated with standardised operations to maximise capacity and efficiency. This enables scalable deployment of private overnight rail without requiring new rolling stock.

The model integrates operational reliability with a hospitality-focused experience inspired by boutique hotels. It is designed to serve both leisure and business travellers by reducing the need for additional hotel stays, minimising travel time, and improving overall comfort and predictability. Founded in 2025 by Thibault Constant, Janek Smalla, and Artur Hasselbach, Nox Mobility brings together experience in rail, mobility platforms, and technology startups.

Night trains are one of Europe’s last big untapped mobility opportunities. The infrastructure already exists, and the market is waiting. Raising this round shows that investors believe in our approach to create a lovable product with a business model that works, said Artur Hasselbach, co-founder of Nox Mobility. With the new funding, Nox Mobility aims to advance product development and establish its position in the evolving European rail landscape, focusing on delivering a more consistent, private, and user-centred overnight travel experience.
