NER Bogie Tank Passenger
Encyclopedia
The North Eastern Railway (NER
) Bogie Tank Passenger (BTP) locomotives were designed by Edward Fletcher
in 1873. The locomotives were for hauling passenger services on branch lines. They had an 0-4-4
wheel layout and were later designated as G6. A total of 124 G6s were built.
With the introduction of the NER Class O
(LNER G5), G6 locomotives started to become redundant. Fifty of the redundant G6s were rebuilt between 1899 and 1908 as NER 290 Class
(later LNER Class J77) 0-6-0T locomotives. In 1903, locomotive No. 957 was rebuilt as a 2-2-4T (later designated LNER Class X2) specifically for hauling an officer's saloon.
Many class BTPs gained a further lease of life in the early 1900's by being converted to work the 'Steam Autocars' then being introduced. A Steam Autocar consisted of a BTP with one or two coaches (in which case the engine was in the middle), the train was driven from a driving compartment in the leading coach, leaving the fireman on the footplate. The driver had control of the regulator and reverser by means of a mechanical connection running under the coach and connecting to the engine using a form of universal joints. The driver also had full (Westinghouse) brake control via a second air pipe connection to the engine. This high pressure air supply also worked a whistle mounted above the driving compartment. Finally there was speaking tube
communication between the driver and fireman - although there is evidence that this was little used.
Steam Autocars were gradually withdrawn as the LNER introduced Sentinel

s. The coaches were converted back to normal coaches but the BTPs were withdrawn.
With the reduction in passenger services towards the end of World War I
, many of the G6s became redundant. In 1921, ten G6s were rebuilt to create further NER 290 Class
. Withdrawals of the G6 took place between 1920 and 1929.

Speaking tube
A speaking tube or voicepipe is a device based on two cones connected by an air pipe through which speech can be transmitted over an extended distance. While its most common use was in intra-ship communications, the principle was also used in fine homes and offices of the 19th century, as well as...
