We are pleased to reveal the latest decorated samples for our New & Exclusive batch of LNER Class A5 2-6-4T steam locomotives from Sonic Models in OO Gauge!
The first batch sold out fast and demand has been high for a new run of these distinctive large tank engines. Four new models are to be produced in Great Central Railway, LNER and British Railways colour schemes. The specification remains the same as the previous batch, although new running numbers have been provided for the most popular liveries.
The Sonic model features a heavy die-cast chassis, flywheel, Next18 DCC socket hidden in the cab, pre-fitted sugar cube speaker, NEM coupling pockets, sprung buffers and all models will be supplied with an accessory pack including coal shovel and rake and dummy screw-link couplers. Detail differences include GCR or LNER dome, whistle and smokebox, 3-rail or 5-rail coal bunker, single or split cab front window, cab-sides open or with windows and smooth or riveted sandbox wrapper.
These models are to be produced in very limited numbers, so pre-ordering is highly recommended. We require a £30 deposit, with the final balance being taken when the locomotives arrive in stock. We currently expect these to arrive during Q3 2025.

Prototype Information

44 of these powerful locomotives were built over a 15 year period from 1911-1926 and the last was withdrawn in 1960.
Designed by the Great Central Railway’s Chief Mechanical Engineer John G Robinson to tackle suburban trains operating from the company’s London terminus at Marylebone, they were originally designated Class 9N, however after grouping the LNER reclassified them A5.
The last-built locomotives, built after grouping, were assigned to north east England and under the LNER other members of the class were used more widely – on suburban services from King Cross, around Bradford and on the former London Transport lines between Aylesbury and Rickmansworth.
Following nationalisation those A5s still on Marylebone trains were transferred to Lincolnshire and on to Darlington and Hull. The last was withdrawn in November 1960.
