Revised 55 and new 56 service Stevenage Letchworth Hitchin

From September 2026 the current 55 service from Stevenage to Letchworth Grange will drop to an hourly service, with a new 56 hourly service between Stevenage and Hitchin via Letchworth Jackmans Estate and town centre. This latter service will finally provide a link to Hitchin without having to change in Letchworth town centre.
