The four elements to be deferred are: • electrification between Didcot Parkway and Oxford • electrification of Filton Bank (Bristol Parkway to Bristol Temple Meads) • electrification west of Thingley Junction near Chippenham to Bath Spa and Bristol Temple Meads, and • electrification of the Henley and Windsor branch lines. While the DfT continued to invest £2.8bn in the GWML electrification programme from London to Bristol Parkway and Cardiff, between £146m to £165m is expected to be saved by these deferrals in this spending period.
