Smallest quality Traction engine available

[Rob1962]

Hello, What is the smallest quality Traction engine available anyone know if there is.

[Boston Lodge]

See www.berrybrooksteam.co.uk and look at the 1" scale Burrell which is gas fired or for something with more detail a 1" scale Fowler class BB1 ploughing engine which is coal fired. Are these small enough?
