• KKR acquires a majority stake in Vienna based Green Mobility Partners to expand electric locomotive leasing across Europe as rail electrification accelerates.
  • The deal targets structural decarbonization gaps in Europe’s ageing, diesel-heavy rail fleet, aligning private capital with EU transport and climate priorities.
  • KKR deepens its European infrastructure exposure after committing over $31 billion globally to energy transition assets since 2011 and roughly $21.7 billion in equity across the DACH region since 1999.

As European governments push to decarbonize transport systems under tightening climate targets, private capital is moving to fill a widening infrastructure gap in rail. KKR has agreed to acquire a majority stake in Green Mobility Partners, a fast-growing electric locomotive leasing company, in a bid to scale a pan-European platform focused on electrified freight and passenger rail.

The partnership pairs KKR’s global infrastructure capital with a young but tightly focused operator. Founded in 2024 by Christoph Katzensteiner, Green Mobility Partners leases Siemens Vectron electric locomotives to rail operators across Continental Europe. The company’s model centres on long-term, contract-backed leasing designed to help operators transition away from diesel without bearing the upfront cost of fleet replacement.

The transaction, subject to customary approvals, will be made through investment vehicles managed by KKR.

Addressing An Ageing And Diesel-Heavy Fleet

Europe’s rail network is under mounting pressure to modernise. While rail is already one of the lowest-emissions transport modes, much of the continent’s locomotive fleet remains diesel-powered, particularly in freight. Ageing rolling stock, fragmented national networks, and uneven electrification have slowed progress just as policy pressure intensifies.

This gap creates a commercial opening for asset-light operators such as GMP, which can supply modern electric locomotives on flexible terms. The company exclusively leases Siemens Vectron models, widely used across European corridors due to their cross-border compatibility.

Katzensteiner framed the deal squarely within Europe’s climate and infrastructure agenda. “Europe’s rail infrastructure requires significant modernisation to meet its decarbonisation objectives,” he said. “I am delighted to partner with KKR to help address these needs and build a leading European rail leasing platform.”

He added that the combination of capital and industry relationships would be decisive. “With KKR’s support and our established relationships with both operators and manufacturers, GMP is ideally positioned to provide the flexible, sustainable infrastructure solutions that Europe’s rail sector urgently needs as it transitions to a low-carbon future.”

Scaling Through Capital And Consolidation

KKR’s investment is designed to support both organic fleet growth and acquisitions, positioning GMP as a consolidator in a fragmented market. Leasing platforms are increasingly viewed by policymakers and operators as a practical mechanism to accelerate electrification without waiting for public procurement cycles or national rail reforms.

For KKR, rail fits a broader strategy focused on hard-to-abate sectors where decarbonisation requires long-dated capital and operational expertise. Vincent Policard, Co-Head of European Infrastructure at KKR, pointed to the structural nature of the opportunity.

“Rail is at a critical moment in Europe, with an ageing fleet that faces significant challenges to modernise,” he said. “Christoph is a trusted founder who knows these challenges better than anyone, and crucially, how to address them.”

Policard described GMP’s business as combining “a resilient, contract-backed business model with powerful secular tailwinds in both locomotive and passenger rail leasing,” adding that KKR’s role would be to provide flexible capital and infrastructure expertise to support expansion.

Fit With Broader Energy Transition Capital Flows

The deal reinforces KKR’s positioning as a major private investor in the energy transition. Since 2011, the firm’s infrastructure platform has committed more than $31 billion globally to renewables and transition-related assets, including electrification-focused investments alongside companies such as Zenobē and Dawsongroup.

Regionally, the transaction builds on KKR’s long-standing presence in the DACH market. The firm has invested roughly $21.7 billion in equity across more than 40 companies in the region since 1999, with over two-thirds alongside founders and family-owned businesses. In infrastructure alone, KKR and its co-investors have committed more than $10.9 billion to DACH over the past three years.

Germany’s renewed emphasis on infrastructure spending, including the launch of a dedicated special infrastructure fund, has further sharpened investor focus on transport and energy assets that support industrial competitiveness and emissions reduction.

What Executives And Investors Should Watch

For C-suite leaders and infrastructure investors, the GMP transaction highlights how rail electrification is shifting from public ambition to investable platform strategies. Leasing models reduce balance sheet strain for operators while accelerating fleet renewal, making them an increasingly central tool in Europe’s transport decarbonisation playbook.

As climate targets tighten and public budgets remain constrained, partnerships between specialised operators and large-scale private capital are likely to play a growing role in determining whether Europe’s rail system can modernise fast enough to meet its climate and economic goals.
