“The East Croydon bottleneck leaves constituents at Norwood Junction station in an unresolved or uncertain situation.”

**Cause identified:** The East Croydon bottleneck (and the associated shelving of the Croydon Area Remodelling Scheme, CARS). **Effect identified:** Constituents at Norwood Junction station are left in an unresolved or uncertain situation ("in limbo"). **Evidence analysis:** 1. **The bottleneck is well-documented.** Network Rail's own page describes bottlenecks in the Croydon area causing delays to "ripple across the network." MyLondon reports that the Selhurst Triangle (between East Croydon, Selhurst, and Norwood Junction) is the busiest railway junction in the UK, with around 67% of trains delayed or cancelled. The minister in a March 2026 Westminster Hall debate acknowledged that "the complex junction at Selhurst—often referred to as the Croydon bottleneck—alongside the challenging operation of East Croydon and Norwood Junction stations, places significant constraints on the capacity and smooth operation of the network." 2. **CARS explicitly included Norwood Junction improvements.** Network Rail's page lists "Norwood Junction station improvements" as part of CARS. The Croydon Council planning document specifies these included "major track layout changes at Norwood Junction, including the introduction of step-free access to all platforms" and a new rolling stock depot south of Norwood Junction. 3. **CARS was shelved, leaving Norwood Junction in limbo.** The scheme was paused at the 2021 Spending Review (though the previous government never formally communicated this to stakeholders). No further development work has occurred since. The Labour government's 2025 spending review also did not allocate funding. MyLondon reporting (March 2026) specifically quotes Natasha Irons saying Network Rail is "not progressing accessible lift plans while the wider scheme remains uncertain," leaving commuters in an "endless cycle of lift limbo" at Norwood Junction — only Platform 1 has step-free access. 4. **The causal chain is clear and well-evidenced.** The East Croydon bottleneck is the underlying problem that necessitated CARS. CARS included specific, needed improvements to Norwood Junction. The shelving of CARS means those improvements are not progressing, leaving the station — particularly its accessibility — in an unresolved state. The minister's response confirmed no funding is currently available and the next opportunity would be the 2027 spending review. The only nuance is that the direct cause of the "limbo" is the political/funding decision to shelve CARS, rather than the bottleneck itself. However, the bottleneck is the root cause that makes the improvements necessary, and without CARS being progressed, Norwood Junction remains in its current constrained state. The claim's framing — that the bottleneck leaves Norwood Junction in limbo — is a reasonable and well-supported characterization of this chain.
