Since last year, ProRail, the Dutch Human Environment and Transport Inspectorate (ILT), Strukton Rail and DB Cargo, in conjunction with Dual Inventive, have been carrying out a pilot with a remotely controlled red signal in the Kijfhoek shunting yard. At the end of February, there was a test day at Kijfhoek to see how train drivers would react to signal 512b. As their reactions were positive, it was decided to move to the next phase of the pilot.
