Marcus joined Rock in July 2024 as Head of Commercial – Germany. Marcus has over 10 years experience in the railway industry. He has worked for train operators as controller, head of controlling and business development and also as project manager, with roles encompassing a broad range of commercial (engineering) activity and rolling stock.

Most recently, as Head of Business Development of Niederbarnimer Eisenbahn (NEB), he was responsible for the “Netz Ostbrandenburg 2” and “Netz Heidekrautbahn 3” transport contracts, having won both transport contracts as the lead responsible for the NEB’s technical and commercial offer. In addition to negotiating the vehicle financing with green bonds, he also managed the technical support with the conclusion of TSSSAs with the vehicle manufacturers.

Marcus’ focus during the tendering process and commissioning was, in addition to the aforementioned focal points, on vehicles with alternative drive systems and the associated infrastructure, including all processes and coordination with approval authorities.

Marcus has an extensive knowledge of operator, financing and vehicle technology experience with which he is an asset to the Rock team and will take a lead role in Rock Rail’s business development and asset management capabilities as it continues to grow its rolling stock portfolio in Germany.

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

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.
