The starting signal Lima Whiskey 012 (LW 12) on Platform 5 at Lewes Station is fitted with a rogue TPWS Loop that keeps triggering brake demand even when the signal is clear. I don't know if there's a reason behind this but if it's not meant to do this it's an annoying bug that necessitates the use of the TPWS train stop override, which against a green would not be necessary in real life.
