The Republic of Irish Government has said it is looking to add a tracking system to the national freight tracking system.
The Government said the new tracking system would allow the Government to ensure that the national transporter, which currently has a pilot freight definition and is required to collect and retain data about all freight and passenger movement, is not being used for illegal activity.
The pilot freight definitions will be expanded to include passenger movements within the Republic as well as freight movement between Ireland and overseas, the Minister for Transport, Tourism and Sport, Paschal Donohoe, said.
It will also include passenger movement between the Republic and the United Kingdom, he added.
The Transport Minister said it would be up to the National Railways and the Department of Transport and Main Roads to decide how they would integrate the new national freight definition into the system.
Currently, there are two types of freight definition: freight and cargo, he said.
A freight definition allows the Transport Minister to decide whether a journey must be freight or cargo based on the specific purpose of the journey.
A cargo definition allows a train to travel between Ireland to the UK and vice versa.
The first type of freight definitions are used by the National Transport Authority (NTA) for the Republic.
The second type of definition, which has been in use since the late 1980s, allows the Government and the NTA to determine the passenger movement that must be recorded.
The government is currently considering how to expand the national definition of freight to include all freight movement.
It is expected to make its final decision by the end of the year, the minister said.
