One of just ten examples of the J52 (formerly GNR J13) built by Robert Stephenson & Co at its works in Newcastle-upon-Tyne. Originally numbered 1225, after the Grouping it was repainted and received the LNER number 4225 in November 1926, which remained until the LNER’s renumbering scheme of 1946, when it became No. 8824 and, subsequently BR No. 68824. The locomotive lasted in service until May 1959, a creditable 60 years in traffic.

The LNER’s standard goods and shunting locomotive livery of plain black with red-shaded lettering and numerals decorates the model, which also has its builder’s plate on the bunker sides.
