About the Tramlink Route 4 — Therapia Lane ↔ Elmers End

Introduced in 2006, Route 4 runs primarily on weekdays from the Therapia Lane depot (where Tramlink trams are stabled overnight) to Elmers End — directly serving major commuting corridors via Wandle Park and IKEA Croydon.

Route 4 shares track with Route 1 east of Sandilands, providing combined frequencies of every 3–5 minutes during peak hours on the busy Croydon–Elmers End section.

The route also serves the IKEA Croydon and Valley Park retail park stops at Ampere Way — heavily used by weekend shoppers.
