Carillion rail were instructed to change an Electrical Power supply from Old Oak Common Feeder feeder station 1 (which is controlled by Rugby ECR) to Old Oak Common feeder Station 2 (which is controlled by Romford ECR) on the Crossrail West OOCPA project. Having known A&M Electricals for a number of years, I knew they had the experience, knowledge and expertise to assist Carillion in carrying out this complex piece of work. The price was extremely competitive, and the on site teams were excellent.
