 Weston Green is also contiguous with Esher, which provides the village's closest railway station.The village forms a rough triangle of land along the west side of the midsection of the Hampton Court Branch Line next to Thames Ditton railway station and down to Esher railway station (which is on the South Western Main Line), with the split between the two being the part dual-carriageway, the A309.The name is derived from Westun, a farmstead covering land in the west of Thames Ditton.
