My vision of Crossrail 2 (the Chelney line upon opening) prioritises the eastern Hackney branch as the main route, and adjusts the northern and southern terminis.
The start of Crossrail 2 would be at Bishops Stortford, with a branch line to Hertford East. A mix of short and full length semi-fast and stopping services travel via Meridian Water and Lea Bridge, to where new underground platforms would replace the current ones at Stratford.
The route then follows underground along the North London line. Two megastation complexes would merge Hackney Central/Hackney Downs (renamed Hackney) and Dalston Junction/Dalston Kingsland (renamed Dalston Junction). A northern route would travel to Welwyn Garden City or Hertford North via Rectory Road, Seven Sisters/South Tottenham, Turnpike Lane and Alexandra Palace, with, like the West Anglia line, a mix of short and long stopping and fast services.
The current planned core section from Dalston to Chelsea would still be adopted. The southern end, however, is dependent on either taking over the Windsor or Wimbledon lines. Limited SWR trains may travel from these destination to Waterloo.
If the Windsor line is opted, then the underground section continues through Imperial Wharf and a new station called Wandsworth Bridge, surfacing near Putney. Crossrail 2 takes over the Weybridge/Woking, Windsor, and Shepperton services, all diverted through the core section.
If the Wimbledon line is opted, the underground section continues to Clapham Junction, Wandsworth Common and Tooting Broadway, surfaces prior to Haydons Road, and to Wimbledon. Crossrail 2 then takes over the Guildford (via Epsom and Claygate), Chessington South, Hampton Court, and Dorking services, all diverted via the core section.
