The Totteridge & Whetstone station was planned by the Edgware, Highgate and London Railway (EH&LR) and was originally opened as Whetstone and Totteridge on 1 April 1872 by the Great Northern Railway (which had taken over the EH&LR) [REF].
After the 1921 Railways Act created the Big Four railway companies the line was, from 1923, part of the London and North Eastern Railway (LNER).
