New Leipzig S-Bahn fleet financed by Rock Rail and Infracapital

The fleet for Lot 2 is made up of 41 Siemens Mireo 3-car trains – coupled with Lot 1, the new Leipzig S-Bahn fleet comprises 195 Siemens Mireo cars, which will enter service in December 2026. The Lot 2 trains will initially be leased to Die Länderbahn GmbH (part of the Netinera Group of Companies in Germany).

The overall fleet will deliver a step-change in passenger experience and uplift to capacity, which will help support Germany’s growing demand for rail travel and transition away from other, less environmentally friendly modes of transport. The design has been specified to deliver all operational requirements of the network including features that support safe operation through the Leipzig Tunnel; optimised floor level to match different platform heights and operational performance for both S-Bahn services on the core section and regional on the outer sections.

The Siemens Mireo platform operates at up to 25% higher energy efficiency than trains with similar capacities and delivers climate-friendly mobility. The fleet will provide step-free access from a standard 550m platform and is designed with a gap bridging plate and sliding step to accommodate TSI PRM compliant access for all platform heights. The train exterior is marked for wheelchair users and bicycle spaces to facilitate passenger flow at busy stations.

These new EMUs will service the following lines:

Lot 1

  • S 4: Torgau – Eilenburg – Taucha – Leipzig Hbf. (lower level) – Oschatz – Riesa
  • S 6: Leipzig-Stötteritz – Leipzig Hbf. (lower level) – Leipzig-Messe – Naumburg
  • S 10: Schkeuditz – Leipzig Hbf. (upper level)

 

Lot 2

  • S 3: Halle Nietleben – Halle Hbf – Leipzig Hbf. (lower level) – Borna – Geithain
  • S 5: Halle Trotha – Halle Hbf – Leipzig/Halle Airport – Leipzig Hbf. (lower level) – Altenburg – Gößnitz – Zwickau or Glauchau
  • S 5X: Halle Trotha – Halle Hbf – Leipzig/Halle Airport – Leipzig Hbf. (lower level) – Altenburg – Werdau – Zwickau or Plauen

 

After its successful launch and now the second transaction in quick succession, Rock Rail and Infracapital will use its German Regional Rail platform to help deliver private infrastructure capital to Germany’s rolling stock market and support the country’s transition to net zero.

Mark Swindell, Chief Executive Officer at Rock Rail, said: “Rock Rail has been working in Germany since 2018 and has strong relationships with all the German regional public authorities, operators and manufacturers. We are delighted to have worked on our second deal in Germany with Infracapital and MEAG to lease Siemens Mireo trains to DB Regio and Die Länderbahn in the beautiful city of Leipzig. This specific opportunity has been 2 years in development and is a testament to the dedication and perseverance of Rock as well as the City of Leipzig. We will continue to work very hard with our operator partners to fund more fleets in Germany with Infracapital over the next few years”.

Priya Veerapen, Managing Director at Infracapital, said: “We are pleased to have secured this follow on investment in the Leipzig Central German S-Bahn Network 2025+ fleet alongside Rock Rail, which builds on our ongoing partnership and ambition to support the delivery of improved sustainable transport systems in a market which holds significant growth potential.”

Benjamin Hemming, Head of Illiquid Assets Debt at MEAG, said: “We are very pleased to support Rock Rail and Infracapital by arranging the senior debt financing for the fleet of Siemens Mireo trains to be deployed on the MDSB2025+ network. This underpins our ambition to substantially contribute to the modernisation of sustainable public transport in Germany. The technically advanced features of the new fleet will allow state-of-the-art passenger experience, increased capacity and an improved environmental footprint“.

Driving Net Zero: How Rock Road 
Is Funding the UK’s Bus Transition

Accelerating the shift to clean, affordable, zero-emission transport

The Challenge

The UK bus network is at the heart of everyday travel – but over 30,000 diesel buses still need replacing to achieve a fully zero-emission fleet.

While around 5,000 battery-electric buses are already on the road, the high upfront cost of electric vehicles and depot electrification continues to slow the transition. Traditional funding routes — such as government grants or short-term bank finance – have helped start the journey but cannot support decarbonisation at the scale required.

A new, sustainable funding model was needed: one that could attract long-term capital, spread costs fairly, and give operators and authorities confidence in the future.

The Solution

In 2021, Rock launched Rock Road to deliver exactly that –  applying its proven infrastructure financing approach from the rail sector to the UK’s clean bus revolution.

Working with Aviva, the National Wealth Fund, and HSBC, Rock created a dedicated investment platform that channels infrastructure-style finance from pension funds and institutional investors directly into zero-emission bus projects.

This model provides:

Impact

The platform has already raised £100 million, with capacity to scale to £1 billion per year over the next decade – providing a consistent source of affordable capital for local authorities and operators.

Rock’s model ensures that the total cost of ownership (TCO) of electric buses can now be lower than diesel equivalents, thanks to both cheaper long-term finance and reduced operating costs.

In London, Rock has financed 120 zero-emission buses under 7-year leases aligned with Transport for London’s contract lengths. This structure gives operators flexibility and certainty:

The Future

Rock Road’s ambition is to support the rollout of zero-emission fleets across the UK – helping local authorities and operators meet climate goals without overextending public budgets.

By leveraging limited government funding to attract large-scale private capital – for example, £10 million of public investment unlocking over £250 million in total funding – Rock’s model accelerates decarbonisation while keeping costs low for the public sector.

Our ambition is to make electric buses the default choice - not because of subsidy, but because they are the best economic and environmental option.
