Aber (short for Abergwyngregyn) was an isolated signal box providing the only intermediate block post between Bangor and Penmaenmawr. During evenings the box was unmanned making it a long block section of some ten miles for such a busy mixed traffic line. The box was located very close to where Aber station was situated. This station was somewhat isolated from the settlements it professed to serve and closed in 1960. The box was a super early example of an L&NWR structure but I have no details of its date of construction unless anybody can help.
