St. Erth signal box is located some short distance east

of the station with the main line passing in front and the St. Ives branch to the rear. For such a small village, the station has always been a pretty busy spot, more so in past years. There were once extensive sidings that were linked to the creamery that sent milk trains over night to London. The creamery closed in 1980, the sidings were lifted and the site became surplus. The site has been cleared in recent years and is now being developed for housing and a brand new car park for the station.
