APIC won the contract with London Underground to replace the capacitors in the Central Line’s dated, unreliable DC traction systems with modern AC traction packages. Currently, almost £8million per year is spent repairing the existing traction motors. By completion in 2022 the AC traction and DTS elements of the overhaul project combined will see:
1. An annual reduction of 836 service affecting failures attributed in the CuPID database to ‘Central line Fleet’, saving 631k Lost Customer Hours with a social benefit of £5.4m per year.
2. An annual reduction of £8m in fleet maintenance costs (£6m material and £2m labour).
3. A net annual reduction in modelled energy consumption of 11GWh, valued at £0.7m, and an annual reduction in CO2 emissions of 5,000 tonnes, with a social value of £23k.
Our bespoke designs and specialist abilities in obsolescent capacitors made us the perfect contender for this project.
