The 2Nol (2-car No Lavatory stock, numbers 1813-1890) units were built in 1935-1936 by taking former LSWR carriage bodies, lengthening them, and placing them on new underframes. They were intended for use on slow services on the South Coast and in South London.
Formations
Initial formations of these units were as follows (carriages were not necessarily formed in numerical order):

Withdrawal
The majority of these units were withdrawn in the mid-1950s, when the old bodies were scrapped and the underframes were re-used for new 2EPB and 2Hap units.
They are less common on the Cathcart Circle line, which is served mainly by the aging class314 units, and the North Clyde line, which is served mainly by the class320 units.
