Today, Colas Rail 70810 made a run between Westbury and Worcester with RILA track measurement equipment attached to its front. This equipment was developed by the Dutch firm Raildata (now part of Fugro) and can be attached to various existing rolling stock (locomotives and multiple units). As a result specially adapted measuring trains are not needed. Attached to regular trains, there is no additional pressure on scarce track capacity on busy routes. More about Raildata here: link.
