This is the Hornby OO Scale BR Class A4 Seagull 60033 - Steam Generator [R30552SS]

60033 ‘Seagull’ was among the four new ‘A4s’ built with double chimney and blastpipe in 1938, the remainder of the class not receiving them until the 1950s. 

First numbered 4902, it was also one of a batch of six new LNER ‘A4s’ to be named after birds, as Sir Nigel Gresley had a particular fondness for breeding wild birds. ‘Seagull’ was one of three ‘A4’ Class ‘Pacifics’ used for the 1948 Locomotive Exchange Trials, in which the newly formed British Railways sought to test locomotives on the routes of other former ‘Big Four’ members, with 60033 working between London Paddington and Plymouth, though it didn’t perform as well as the GWR locomotives that were designed for the route. 

The locomotive was withdrawn in December 1962 and scrapped at Doncaster the following year. In 2026 we have given the A4 a tooling update and the model now includes the new Hornby steam generator technology, working headlights and tender lights.
