And whether they could have done better . . . .

<Footer>2

Docklands Light Railway

• Initial system built quickly to a low spec

• 2 years lost as LT failed to grasp the changed reality

• Missed opportunities and design mistakes

• Still a great success

Jubilee Line Extension

• Mistaken (?) political controversy

• 4 years delay due to funding

• Missed opportunities and design mistakes

• Still a great success

Crossrail

• Hasty design that became “locked in”

• 20 years delay – but little improvement in the scheme

Originally a surface LRT line

Development of the Strategic Specification

3.1 The original Crossrail scheme was developedin the late 1980s and while some of theoriginal objectives remain, in particular therelief of crowding on the National Rail andUnderground networks in central London,some have evolved over time. Critically, sincethen, Docklands regeneration and growthambitions have come to fruition and have nowbeen extended into the wider ThamesGateway area. While the Jubilee Lineextension and Docklands Light Railway(DLR) have been developed around theemerging pattern of demand in East London,there has been a sustained period of growth,both in population and employment.

3.2 The original Crossrail concept was focused on central London’s problems but now theconsideration is much wider. CentralLondon’s economy is of very greatsignificance nationally and extending itsalready substantial job catchment area andimproving the efficiency and dependability ofaccess journeys is a very important feature ofthe revised Crossrail proposal.

The Crossrail BenchmarkScheme – Service Pattern

3.3 Crossrail would operate a 24 trains per hour(tph) peak service in both directions throughcentral London between Whitechapel andPaddington, with branches in the east fromEbbsfleet and Shenfield and in the west fromHeathrow and Kingston.

3.4 Although the precise service pattern on Crossrail is still under development,particularly on the west London routes,the Crossrail proposal presented here hasbeen termed the “benchmark scheme”.The peak period Crossrail service frequenciesunderlying this scheme are shown in Figure3.1 and assume:

• 12 tph service from Shenfield, replacing much of the existing Great EasternMetro service

• 12 tph service from the North Kent line,with 4 tph originating from Ebbsfleet and 8 tph from Abbey Wood

• 6 tph service from Heathrow Airport, thatreplace the current 4 tph Heathrow Express service

• 12 tph service from the Kingston branch,with 4 tph originating from Kingston and 8 tph from Richmond.

3. The Crossrail Proposal

3.5 Crossrail services would generally operate as“all stations” services, although a number oflesser-used stations along the corridor wouldbe omitted. In addition, services to and fromHeathrow Airport would call only at Hayes &Harlington and Ealing Broadway to the west of Paddington.

3.6 In the east, provision has been made for thecurrent North London line service to use the route between Custom House and AbbeyWood. This service would be rerouted to start at Abbey Wood with Silvertown andNorth Woolwich stations being closed.This area would benefit from the DLRextension to London City Airport and KingGeorge V, currently under construction.

3.7 In the west, the definition of the Crossrailservice to both Kingston and Heathrow is still in progress, with the precise Heathrowdefinition subject to achieving agreementwith BAA plc. Opportunities are also beingexplored to further enhance the benefits of the Kingston branch by providing anadditional interchange at either Chiswick Park or Turnham Green.
