A similar collection of signals serving the same purposes as the previous photo. But also visible in this picture is the Signalphone (the white box with black diagonal stripes) which allows direct contact (in this case) with the signal operator in the Control Room at Earls Court. The white board with a letter 'D' reminds drivers (in this instance) that deicing equipment should be switched off. If reversed it states 'D On' - the equipment should be turned on. Also visible is a reminder to drivers to use the Public Address before departing and another board marked 'Train Operator Information'. This is used like a white board to post up any relevant short term information to drivers.
