The Tennant J74 (NER Class 8) 0-6-0 Tank Engines
McDonnell's resignation in September 1884 forced the
North Eastern Railway (NER) to form a 'caretaker' Locomotive Committee chaired by
Henry Tennant to handle the
duties of a Locomotive Superintendent.
This Committee quickly designed the very successful
E5 2-4-0 (NER '1463') class, to replace
McDonnell's troublesome
'38' Class 4-4-0.
Material for eight further
'38's had been ordered, and the Committee chose to use the
surplus parts to build eight side tank shunters. These eight engines were built in 1885 and were given the
NER classification of Class 8.
They had a number of unusual features including rounded fronts to their side tanks, and
McDonnell-style brass beading around the combined front
sandbox and splasher.
The original boilers were some of the last NER boilers which were built with iron plates. Records are poor, but they
are thought to have had similar dimensions to the boilers fitted to the
McDonnell J22 (NER '59')
and NER '38' locomotives.
Standard Worsdell boiler replacements were fitted
between 1900 and 1905.
The J74s appear to have never been held in particularly high regard, and no official photograph of a J74 exists.
Initial allocations were to Tyne Dock and Borough Gardens. A large influx of J72s in the
early 1920s led to them being displaced to Alexandra Dock shed (Hull). At Hull, they replaced
Hull & Barnsley locomotives which were condemned by the NER at the first opportunity.
The J74s continued to shunt the docks at Alexandra for the rest of their lives.
The first J74 was withdrawn in February 1930, and the remainder in 1931. No. 662 was sold to
Ashington Coal Co. where it became their No. 5, and was eventually scrapped in 1938.
