Styria backs electrification plan for Murtalbahn railway

The government of Styria has approved a package to electrify the Murtalbahn narrow-gauge railway and procure a new fleet of vehicles, signaling a long-term commitment to modernizing one of Austria’s best-known regional lines and cutting diesel emissions in the Mur Valley.

A strategic shift for a historic narrow-gauge line

The Murtalbahn, a 760-millimeter narrow-gauge railway running from Unzmarkt in Styria to Tamsweg in Salzburg, has operated for more than a century as a largely diesel-powered regional route and tourist attraction. Publicly available information shows that the 76-kilometer line is one of Austria’s longest narrow-gauge railways and is managed by Steiermärkische Landesbahnen, the state-owned regional operator.

According to regional transport documents and published coverage in Austrian media, the Styrian government has now endorsed an investment program that includes full route electrification and the acquisition of modern electric multiple units for passenger services. The decision embeds the Murtalbahn within a wider push to decarbonize regional rail in Austria, where national and provincial authorities are gradually phasing out diesel on non-electrified lines.

Reports indicate that the approval secures the political framework and funding commitment needed to move from feasibility planning into detailed design, permitting and procurement. Implementation will still depend on further technical studies, tendering and coordination with neighboring Salzburg, but the regional green light is being interpreted as a milestone for the line’s future.

Infrastructure upgrade: from diesel to electric operation

Electrifying the Murtalbahn will require a comprehensive renewal of infrastructure along the valley of the River Mur. Public tender information and previous planning studies for similar Austrian projects suggest that work is likely to include the installation of overhead contact lines, new or upgraded substations, adjustments to bridges and tunnels, and modernization of signaling and safety systems.

The narrow-gauge profile of the route, together with its mix of local commuter traffic and seasonal tourist flows, has historically made major upgrades complex. However, recent experience on other European narrow-gauge lines, such as the Mariazell Railway in eastern Austria, shows that electrification can be combined with heritage operations when infrastructure is carefully designed and powered rolling stock is selected to fit existing clearances.

Regional planning material indicates that construction on the Murtalbahn will be phased to limit disruption to daily services. Partial closures, temporary bus replacement services and targeted work windows during off-peak periods are expected as typical tools, although the exact construction schedule has not yet been published. Authorities are also expected to review level crossings, station platforms and accessibility features as part of the broader modernization package.

New vehicle fleet to replace aging diesel trains

Alongside electrification, the Styrian program foresees the purchase of a new fleet of vehicles tailored to the Murtalbahn’s narrow-gauge infrastructure. While final technical specifications have not yet been made public, industry reports and comparisons with recent orders on other Austrian and Italian narrow-gauge systems suggest the trains are likely to be low-floor electric multiple units with space for bicycles, pushchairs and passengers with reduced mobility.

Existing diesel multiple units on the line date from an earlier era of regional rail policy and lack the energy efficiency, acceleration and modern passenger amenities of contemporary rolling stock. By moving to electric units, the operator is expected to benefit from lower operating costs per train-kilometer over the long term, more consistent performance on steep gradients and reduced noise in communities along the route.

Procurement is likely to be carried out through a competitive tender with European manufacturers that specialize in narrow-gauge equipment. Experiences from similar projects show a growing market for bespoke low-emission trains designed for regional and tourist lines, including battery-electric and hydrogen-powered options, although Styria’s latest decision explicitly centers on conventional catenary electrification.

Climate targets and regional mobility goals

The Murtalbahn initiative aligns with Austria’s broader climate and transport strategies, which emphasize shifting passenger journeys from road to rail and cutting greenhouse-gas emissions from regional mobility. Published federal and provincial planning documents highlight rail electrification as a core tool for reducing diesel use, particularly on lines that support daily commuting and tourism.

By decarbonizing a key east–west corridor in the upper Mur Valley, the project is expected to deliver additional benefits beyond direct emission reductions. Local authorities have long framed the line as an economic artery for the Murau region, supporting residents, schools, local industry and alpine tourism. Electric operation, combined with more frequent and reliable services, is seen as a way to strengthen that role and attract new riders who might otherwise rely on private cars.

Environmental groups in Styria have repeatedly argued that investing in existing rail corridors can help contain road traffic growth, limit landscape impacts from highway expansion and support noise reduction in valley communities. With formal approval for electrification and new trains, the Murtalbahn is now positioned to become a flagship regional case study in how small-scale railways can contribute to climate targets while preserving local character.

Next steps and timeline expectations

Following the political approval in Graz, the project now moves into a more detailed planning and financing phase. According to budget documents and previous statements by regional planning bodies, Styria intends to draw on a mix of provincial funds, federal contributions and potential EU instruments that support low-emission transport infrastructure.

Timelines circulating in regional media point to a multi-year implementation horizon, reflecting the technical challenges of upgrading an operating narrow-gauge corridor through mountain terrain. Early steps are likely to include environmental assessments, route-by-route engineering surveys and consultations with municipalities along the line.

Observers note that the Murtalbahn decision fits into a sequence of recent rail investments in Styria, from new electric operations on standard-gauge regional lines to rolling-stock renewals for freight services. If planning proceeds as anticipated, construction on the Murtalbahn could start later in the decade, with electric services and new trains entering traffic after a staged commissioning process.

For passengers, the most visible changes will arrive once the first modern trainsets begin to replace existing diesel units. For Styria’s transport planners, however, the latest approval is already being viewed as a turning point that secures the Murtalbahn’s role in the province’s long-term, low-emission mobility network.
