The ac is distributed from certain relay rooms and from power signal boxes, on the GWML▸ (Great Western Main Line) these have a supply from the DNO▸ (Distribution Network Operator) (electricity supply from the street) and a diesel generator which starts on mains fail.  The power goes from these relay room / power signal boxes to other relay rooms and to some of location cabinets along site the railway from these supplies at a lower voltage then power the local equipment
