Summer Saturdays used to be a Liverpool St to Sheringham and return, formed by 3 x 2car Cravens units from Finsbury Park depot, frequently late coming over to Liverpool Street or reduced to 2 x 2 cars due to GN unit problems. Imagine that distance with units mostly flat out and everything rattling (seats, windows, luggage racks, interior sliding doors) as everything did on those units. At least cleared their works out having spent all their time pottering around on Kings Cross suburban duties. A wonderful journey if one could get a seat behind the driver. I presume they reversed at Norwich as a crew change would have ben necessary there. Also Summer Saturdays Liverpool St to Yarmouth South Town and via East Suffolk line, reversing at Lowestoft, 2 x 3 car Lea Valley units which I don't think had toilets! Imagine families with little children going on holiday and no loos for hours. Another great journey if in the best seats bhind the driver - dire otherwise.
