Innovative wagons for Rohrdorfer Group

The family company in Rohrdorf has been producing cement since 1930. To do this, they require sand. Strictly speaking, slag sand which they obtain from the voestalpine recycling centre. And how? Environmentally friendly by rail, of course 🙂

We move around 1 million tonnes a year for Rohrdorfer Group with the cement plants in Rohrdorf and Gmunden. From limestone to slag sand and loose cements, different equipment solutions are used to ensure the raw material supply for both cement plants

Slag sand has been transported from Linz to Bavaria for many years now.

However, this method of transportation has recently become more innovative than ever before – why? Because we have developed a new transportation option in conjunction with Innofreight and Rohrdorfer Group. The RockTainer SAND. ⬇

The new RockTainer SAND is an enhancement of RockTainer ORE.

What benefits does the RockTainer SAND offer compared to the wagons that have been used to date?
We asked Michael Fellier, our key account manager for building materials:

The new RockTainer SAND are motoring past RockTainer ORE 🙂

The new Innowagen containers and wagons can transport approx. 15% more sand per train with the same number of wagons. The train now travels with 1200 net tonnes and 1600 gross tonnes.

However, the new RockTainer SAND doesn’t just carry a higher volume than its predecessor. What is also special about it is that the new modular wagon, container and transhipment concept optimised in conjunction with Innofreight enables the efficient combination of rail and road transport. This means that the lower part (the Innowagen) and the structure which is filled with sand can be used separately, i.e. flexibly. It is therefore also possible for the wagons to be used more flexibly for shipments of other goods to be transported from the coal and steel, raw materials, chemistry, agricultural, building materials, wood and wood chips industry sectors, but palletised goods can also be used.

The special (rotating) unloading technology of the container also enables secure and quick unloading and an increase to the additional load of transported goods by up to 20%. Core of technological progress: The use of special containers is adapted to the relevant industry and is therefore coordinated to your individual needs, as the containers are used according to your requirements such as specific bulk density or the unloading situation.

In short:

  • 80ft lightweight container-carrying wagon
  • Replaceable container or special container and standard container
  • Multifunctional and flexible usage – adapted to your requirements and the goods being transported
  • Efficient combination of rail and road
  • Innovative unloading technology enables rapid unloading while simultaneously increasing profitability
  • Supply chain from A to Z

Examples for the different container solutions:

But back to transportation.
How is the slag sand now transported from Linz to Bavaria?

At voestalpine, the slag sand is filled into the new containers with huge loading equipment and…




… sent on its way.





Once it reaches Bavaria, the specialists of Rohrdorfer Group are responsible for unloading…



…and sending the empty wagons back to Linz.


And how is the cement produced?

Rohrdorfer Group has kindly provided us with a very clear diagram (on which a train delivery is also recorded :-))

“We enjoy an excellent long-term cooperation,” says a satisfied Michael Fellier

We are proud of the jointly-developed innovative equipment solution through the excellent cooperation with Rohrdorfer Group and look forward to helping them with environmentally friendly transportation for many years to come.
