Followed by a summer view and a much smarter looking box!

Michael was told that one of the relief signalmen had asked if he could paint the box and when it was OK'd asked about colours and was told to make his own choice! At the time a work in progress. The "enamel" signs were in fact made from plywood.

The lever frame inside Berwick signalbox. The white levers are "spares" that would, in days gone by, have been used to control the sidings that were here.

Note the black chain on the left of the photo which has a wheel at the top that it is wound round. This is so that the length of a signal wire can be adjusted to allow for expansion and contraction caused when the temperature varies. On a long wire pull this can be quite noticeable.

The three red "blocks" on each of the levers seventh and eighth from the right are lever collars, used as reminder devices when it is necessary to prevent the levers being pulled.

Berwick Box The Up direction block instrument. This is a standard three-wire, three-position instrument with both block indicators showing "line clear" The upper indicator shows that a Down train from Berwick has been accepted by Polegate Crossing, whilst the lower indicator shows that an up train from Polegate Crossing has been accepted by Berwick, but neither train has as yet entered the section. When the down train enters section towards Polegate Crossing the Signalman will send the Train Entering Section signal whereupon the Polegate Crossing Signalman will acknowledge this signal and turn his commutator (the round knob with a white stripe) to the left, thereby setting his lower and the Berwick's upper Indicators to Train on Line. When the train has arrived at Polegate Crossing, and has been seen to be complete, the Signalman there will place the Block Instruments to the Normal position (by re-setting his commutator to the upright position) and send Train Out of Section to Berwick. Similarly, when the up train leaves Polegate Crossing the Signalman there will send the Train Entering Section signal to Berwick where the Signalman will turn his commutator to the left, thereby setting his lower and the Polegate Crossing's upper Indicators to Train on Line. Once the train is clear of the section the Berwick Signalman will reset his commutator to the Normal position and send Train Out of Section to Polegate Crossing.

The Signalbox Diagram showing how Berwick controls the up line as far as the Glynde Up Starting signal (at which point Lewes box takes over) but only oversees the down line from immediately after the junction of the Newhaven and Seaford branch to his Home signal. As can be seen from the illumination, there is a train on the yellow track circuit.

The duster under the diagram is for use each time a lever is moved. Being made of steel they would soon suffer from perspiration were the Signalman to use just his hands!
