Legion

In response to the planned expansion of the East London Line and the increased demand associated with it, Legion undertook three studies for the East London Line Project and Interfleet. The studies were designed to help:

• Select the best rolling stock
• Configure the rolling stock
• Plan future timetables

We simulated boarding and alighting for the top five proposed models of rolling stock. The aim was to measure and compare the varying Effective Door Open Times (EDOT) of each type of rolling stock and to rank them according to efficiency and capacity. We simulated the rolling stock using a wide range of demand scenarios, including ‘worst case’ levels of demand.

In the second stage of the project, we simulated boarding and alighting scenarios for the preferred rolling stock but this time using different physical configurations for the carriages and comparing different levels of demand at 11 key stations on the East London Line.

The final stage of the project involved studying northbound and southbound dwell times for each station on the East London Line, using the preferred rolling stock and different possible demand scenarios. Findings from these studies are being used by the East London Line Project to design the optimal timetable.
