The London and North Western Railway (LNWR) Special Tank was a class of {{whyte|0-6-0|ST}} steam locomotive.{{Cite web |title=London & Northwestern Railway Preservation Society |url=http://www.lnwrs.org.uk/GoodsLocos/Loco04.php |access-date=9 September 2003}}{{Cite book |last=Casserley |first=H.

A total of 278 locomotives were built from 1870 onwards, of which five survived to be inherited by British Railways in 1948.{{Cite book |last=Longworth |first=Hugh |title=British Railway (sic) Steam Locomotives 1948-1968 |publisher=Ian Allan Publishing |isbn=978-0860936602 |edition=2nd |publication-date=7 November 2013}} These five were in departmental stock:

• Four – numbered 3 (né 317), 6, 7 (2329) and 8 Earlstown (2359) – as Carriage Department shunters at Wolverton Works
• No. 3323 (né 2322 May 1878), a shunter at Crewe Works.

No members of the class remain under preservation, as all were scrapped.
