Newhaven Marine railway station's signal - 18.4.2015

Photographed for a railway-orientated website, I wonder if anyone is aware of other semaphore signals still in use on current railway lines, in Sussex. There used to be a great set at the east end of Hastings station* until fairly recently, but they are all being replaced by colour-light signals, operated from a few regional signalling centres.

Newhaven's third station, Newhaven Marine, is the old boat train terminal and, I believe, is still listed as an open station. If you book from there you get a cab from there to the Town station as the building is unsafe.
