Extra-large car transporting trailers became possible to forward on the Kiskundorozsma-Wels route for the company. Rail Cargo Hungaria Zrt. has never done such forwarding on RO-LA trains. with the consent of the authorities and Pályavasút the trailers started to be transported on this route. This allows Rail Cargo Hungaria to expect a significant traffic increase in the future.
In 2010, Hungarokombi noted that they would like to widen their palette of lorry types transported on RO-LA trains and plans to transport car transportation trailers on the Wels-Kiskundorozsma-Wels route. At the technical meeting which was organized in order to start the traffic, a decision was passed on commuting a special test train to which Pályavasút gave a permission after completing all the specified conditions.
