Recommendations
Short term
The short-term improvements are mainly minor enhancements to improve performance, but include the extension of the bay platform at Grays to accommodate 8-car trains.Medium term (2009–14)
Thameside route: Minor infrastructure works and additional rolling stock to allow all main line peak-service trains to be extended progressively to 12-car formation; the extension of platforms on the Tilbury loop and Ockendon branch to handle 12 cars, to allow all main line peak-service trains to be extended progressively to 8 or 12-car formation. Great Eastern route: All services to include a stop at Stratford, requiring a platform extension, to provide improved connectivity with TfL's system, to even out the peak flows, and release additional paths on the route; three additional trains per hour (tph) in each peak 3-hour period (12-car in the high peaks, 8 in the shoulder peaks), one from Colchester, one from Chelmsford, one from Southend; extending peak hour Southminster branch trains to 12-car; minor infrastructure works and replacement rolling stock in 5-car formation to provide more seats in the peak on the main line to Norwich; construction of a turnback facility at Chadwell Heath, to extend existing and additional morning peak services, and provide a regulating facility during times of disruption; power supply to be enhanced for some of these options. West Anglia route: The extension of remaining non-compliant platforms on the Liverpool Street-Cambridge route and at Stansted Airport to handle 12 cars; the reinstatement of 9-car trains in the peaks on the Hertford East, Enfield Town, Cheshunt via Southbury and Chingford branch services, requiring a small amount of infrastructure; a shuttle service between Cheshunt and Seven Sisters, where a power-operated turnback would be provided, and where interchange with London Underground is available, should be introduced during the peaks; stabling and maintenance facilities for the larger, enhanced fleet; removal of the three level crossings between Tottenham Hale and Waltham Cross; power supply to be enhanced for some of these options and likely future requirements. Freight Accommodating growth in freight traffic, predominantly containers from the Haven ports, mainly via theLonger term (to 2019, and beyond)
Thameside route Continued lengthening of (mainly shoulder) peak trains to 12-car formation. Great Eastern route Continued lengthening of (mainly shoulder) peak trains to 12-car formation; additional stabling facilities. West Anglia Four-tracking of the route between Coppermill Junction (south of Tottenham Hale station) and Broxbourne junction, where the Cambridge/Stansted and Hertford East lines diverge; an additional tunnel and platform edge on the Stansted Airport branch; 1 additional tph serving Stansted; up to six peak time extra tph, including four into Stratford as a terminus; after Crossrail implementation (which releases GE paths between Liverpool Street and Stratford) extending these Stratford services to Liverpool Street, and diverting some Chingford services via a reinstated Hall Farm Curve and Stratford, in turn releasing paths between Hackney Downs and Bethnal Green. Freight Accommodating further growth in freight traffic, including higher capacity in the Leicester area in line with scheduled resignalling. Crossrail Within this timeframe the east-west London Crossrail project is scheduled to be opened; this will subsume GE inner suburban services at 10-car formation.Combined effect through time by route
The benefit cost ratios of the recommendations over time is estimated as: * Thameside route: 3.3 * Great Eastern route: 5.7 * West Anglia (with substantially higher investment costs): 2.7 (including wider economic benefits)Subsequent developments
