for mixed-traffic use. It was Gresley's last design for the LNER before he died in 1941. The V4s had similarities in their appearance and mechanical layout to the
V2 "Green Arrow" class. The V2s, introduced some years before, were large and heavy locomotives, with very limited route availability. The V4 was a lightweight alternative, suitable for use over the whole of the LNER network.

Two locomotives were built at the LNER's

Performance
The type was tried on the Great Eastern section of the LNER, and was well received, with more power than the existing
B17s and better riding qualities. It was anticipated that many more would be produced, but after the death of Gresley and his succession by
Edward Thompson, no more were built. Instead, the

was adopted as the LNER's standard mixed-traffic locomotive.
Service in Scotland

, although their wheel arrangement was not particularly suitable for the steep gradients on the line. They were renumbered 1700 and 1701 in 1946, and later became
British Railways 61700 and 61701.
Withdrawal
Both were scrapped in 1957 when their boilers became due for renewal.
New Build V4
At the A1 Steam Locomotive Trust Silver Jubilee Convention, it was announced that after the completion of no. 2007 "Prince of Wales", they would begin construction on a new V4 which will be number 3403 (61702) Anon. On the 6th of September, 2018, the A1 Trust officially announced that it had started the pre-launch stage for project, with a projected cost of £3 million, and an estimated starting date of 2021. The project is estimated to take around 5 years. There are already parts for the V4 at Darlington Locomotive Works, including a complete set of tyres (originally made for a group in the 1990s who planned to build a V4), a chimney, and the speedometer drives from a
British Rail Class 08. In October of 2022, the A1 Steam Locomotive Trust announced that No. 3403 will be named ''Highlander''.
