... thought somebody might find an example! Thanks Chris & Chris.
Would these be worked by separate levers, or selected automatically according to the state of the line?

Mike,

In the case of Bolton East Junction, the relevant subsidiary signals (there were 4 of them) were worked by one lever each. The 'C' & 'W' indications were selected automatically according to the state of the line ahead, but plungers were provided to operate the 'S' indications.

Chris.

Yes, I thought you would need to tell the equipment if you wanted an a "S". A plunger seems to be a good way of keeping it down to a single lever.

The Westbury North examples were separate levers.
