CASE STUDY

technical & practice

Upton Park provides eastbound and westbound services on the District and Hammersmith & City lines. The station has two above-ground platforms, accessed by stairs leading down from a compact concourse that provides access to Queens Road and Green Street. The station is situated 500m from Upton Park, home to West Ham Football Club, and on match days the station becomes congested, particularly so before the game. Accordingly, London Underground's station capacity team commissioned feasibility design work to explore potential congestion-relief schemes.

Two potential designs for the station were tested under match-day conditions, using Legion software. Both schemes performed better than the current condition, with approximately 40 per cent of the improvements accruing on the concourse.At concourse level, a standard density limit set by LUL was rarely exceeded in either scheme. One option performed significantly better than the other.

The study also identified refinements to this scheme to eliminate cross-flows on the concourse.

However, neither option reduced congestion or customer delay at platform level at the base of the stairs leading up to the concourse during simulated pre-match conditions.

The Legion simulation study used CAD drawings of the station as the basis for the Legion models.
