Climate-friendly ef­fi­ciency

A wide range of drive types is now available: HVO-compatible internal combustion engines with exhaust after-treatment, alternative drive systems with electricity from the overhead contact line or battery systems, hydraulic and electric work units, and combinations of these – this year's iaf will showcase a new level of possibilities.

For over ten years, E³ has stood for economic - ecologic - ergonomic: three key pillars for the success of this innovative machine series. Economic, environmental, and ergonomic benefits come together in synergy. The E³ range already covers tamping, ballast distribution and ballast profiling, stabilization of tracks and turnouts as well as overhead contact line construction and maintenance.

Baneservice Norway receives two universal tamping machines with the eco-friendly E³ drive system. The 15 kV AC network of the overhead contact line supplies the machine system with power. The versatile 2X-4x4 tamping units for plain-line track and turnouts, sleeper-end ballast consolidators and axle drives are electrically powered. The new design offers plenty of space for a safe working environment. It includes a crew area, kitchen, workshop cab, and incinerating toilet, and it simplifies servicing. The UnimatExpress E³ offers a drive system with power being supplied from the overhead contact line for either one or two traction current systems (C/I or CC/I).

A long-established British company has opted for a combination of modern internal combustion engines and electric drive units, ordering four new Unimat 08-4x4/4S machines with electric tamping units. With the experience machine operators have gained over decades, they are able to operate and service the machine. However, the advantages of electric drive technology quickly become apparent: less noise pollution, lower fuel and hydraulic oil consumption, and less wear. The combination with modern internal combustion engines also makes it easy to switch to environmentally friendly HVO fuels.

The Plasser MultiCrafter 15.4 E³ is a multifunctional powerhouse with an emission-free drive system. It offers maximum flexibility and optimum performance in use, from working with a crane and personnel basket to snow removal equipment. The basic structure of the carrier vehicle is identical to other machine designs, which simplifies spare part storage. The MultiCrafter can tow a trailing load of up to 900 tonnes and uses three power sources: overhead contact line, traction batteries, and a diesel-electric power pack. The all-electric drivetrain enables wear-free braking and energy recovery. The comprehensive equipment includes a powerful railway crane, a large loading platform, and snow removal equipment.
