Telegraph block instrument, Walker’s patent ‘Electro-Magnetic Telegraph Semaphore Signal’, one-wire two-position absolute block instrument, Stockton & Darlington Railway number 162, lower enamel plate records the number as 161 which may reflect an error in the S&DR telegraph workshop when delivered. The later ivorine plate is misleading as it gives the 1855 date of the first Walker instrument but this is a later style of 1865. The Stockton & Darlington Railway, in fact the "Darlington Section" of the North Eastern Railway in the transition years 1863 to 1873 introduced Walker's block instruments in 1865, over five years before the rest of the North Eastern Railway. Alfred O Walker was the S&DR Telegraph Superintendent and was CV Walker's younger (half) brother.
