During peak times, Great Northern runs additional stopping services between Kings Cross and Letchworth Garden City. Typically, these units do a few runs before stabling at Letchworth Carriage Sidings for the off peak before returning to service in the evening. They follow the same stopping pattern as their 2CXX London to Cambridge services as far as Letchworth.
