Blue flags at Bolton

Bolton Shops now has blue flag lanterns in place for use when servicing equipment. The shops has five "parking spaces" for equipment - two inside, three outside. A pair of blue LEDs has been installed between the ties at the end of each space, wired to a panel switch. The top of the LED has a cap of black paint to give it a lantern-like appearance. Now when a loco or car is being serviced, the blue flag lanterns can be switched on to alert workers.
