This tiny site is consists of the old station platform and surrounding track bed of ballast and chalk are are favourites with Common Blue and other grassland species species including Small Heath. The platform has overgrown with shrub along with surrounding overgrown Hedgerows and the open mosaic of yard area has been badly damaged by railway operations . Wall Brown used to be common and Dingy Skipper was seen but not in recent years.

Sections:

The Vannesids very much favour the well lit hedgerow with tall herbs of S1 bordering the field while Speckled Woods prefer the shady trackside woodland of S4+5. S4 is also a favourite for Gatekeepers, Holy Blue Meadow Browns and Orange tips. Common Blue prefers the open area of old track-bed S1. The old platform previously the centre of butterfly action is now overgrown. The site is beginning to scrub up and teh beds of Birds foot trefoil are much reduced.
