 Nobody at Wotton could operate the locomotive so a horse had to be hired from Aylesbury until the driver arrived.After the delivery of the second locomotive on 7 September 1872, all passenger services were drawn by locomotive except on Thursdays, when locomotives were replaced by horses to allow for maintenance.The line carried 104 passengers in January 1872, rising to 224 in April, and 456 in August 1872.
