West St Leonards railway station is on the main London - Tunbridge Wells - Hastings line in East Sussex, and is one of four stations that serve Hastings.
It is just north of St Leonards West Marina railway station (another cache of mine) - a now disused station that was the earliest station serving the area.
The Hastings Line (operated by Southeastern) joins the East Coastway Line (operated by Southern) immediately east of West St Leonards, at Bo-Peep junction, just before entering Bo-Peep tunnel. Plans were made for platforms to be built on the East Coastway Line for interchange but Hastings Borough Council decided that there was no economic or passenger benefit as interchange was already available at the next station (Warrior Square).
The cache is located in a high-density muggle area. Use extreme stealth, and consider coming here at night or off-peak times. The cache is not located on railway property. Please don't search in the station.
