In 1939, Sir Nigel Gresley of the London and North Eastern Railway was planning further expansion of the steam locomotive fleet. A new version of the A4 was planned, with a working pressure of 275 psi, as well as a huge 4-8-2 express passenger locomotive. A third design was produced, a small 2-6-2 with a very light axle loading, for service across most of the LNER.

Of the three designs, the latter was chosen and classified class V4. It was to be Gresley's last design for the LNER as he unfortunately passed away in 1941. The V4 was a mixed traffic engine, and by their appearance were assumed to be smaller versions of the green arrow class, although in reality there was little similarity in the designs. The first engine 3401 'Bantam Cock' had a scaled down version of the Standard Gresley Pacific boiler with a grate area of 27.5 sq ft. Its tractive effort of 27,000 lbs was borne from its boiler pressure of 250 psi and three cylinders of 15" diameter. A second locomotive was built, 3402, and this incorporated a steel, fully welded firebox and a single thermic syphon for water circulation.

The engines were very well recieved on the Great Eastern section of the LNER^{[citation needed]}, with more power than the existing B17's and better riding qualities. It was hoped that many more would be produced, but with the death of Gresley and his succesion by Edward Thompson, no more were and both existing engines were sent to Scotland, where there wheel arrangement was not suitable for steep gradients. As a result the engines were finally scrapped.
