Collis Engineering have successfully completed the audit process on its provisional principal contractor licence project at North London Lines. Following this process Collis have been awarded a full licence, which is available to be viewed on our assurance page. Collis looks forward to working ever closer with Network Rail as we progress through 2020, CP6 and beyond.     

Many thanks to our industry partners in helping deliver this project – Pod Trak, SigTech & Network Rail WD.
