The London and North Western Railway (LNWR) Special Tank was a class of 0-6-0ST steam locomotive.

[1][2][3] They were a saddle tank version of the LNWR DX Goods class.

A total of 278 locomotives were built from 1870 onwards, of which five survived to be inherited by British Railways in 1948.

[4] These five were in departmental stock: No members of the class remain under preservation, as all were scrapped.
