Railway station on the London Overground in Travelcard Zone 3. It was opened 1872.
The station takes its name from the street so called which is recorded thus c.1630 and which possibly alludes to silversmiths living here at that date or in earlier times. The street used to include the part of Sterling Way which now runs past the station.
