The London and North Eastern Railway Class A2/2 was a Class of six 4-6-2 steam locomotives rebuilt by Edward Thompson in 1943 and 1944 from his predecessor’s P2 Class of 2-8-2 express passenger locomotives. Withdrawals began in 1959 with 605 ‘Thane of Fife’ in 1959, followed by ‘Lord President’ , and ‘Cock O’ the North in 1960.
Thompson Class A2-2 ‘Cock O the North’ is the latest detailed locomotive to be produced with Hornby’s innovative steam generator functionality where the locomotive creates realistic steam from the chimney of the model created by water vapour. 
This locomotive also comes fitted with sound. It has a series of sounds true to this class of locomotive and the sounds and steam effects are synced to the model's movement, creating a realistic ‘chugging’. 
The model also comes with extra detail such as sprung buffers, a die-cast footplate and a visual flickering firebox emulating the look of a real fire inside the locomotive. This is all controlled by the pre-installed HM7000 21-pin decoder which can then be operated by either DCC or Bluetooth via the free HM7000 app.
