The [[London, Midland and Scottish Railway]] (LMS) '''Fowler Dock Tank''' was an {{whyte|0-6-0|T}} [[steam locomotive]]. Designed for [[Shunting (rail)|shunting]] in [[dock (maritime)|dock]]s, it had a short [[wheelbase]] in order for it to easily negotiate tight curves. The locomotives spent their entire lives painted in plain black.

==History==
The LMS operated lines on a number of docks which due to space constraints contained curves considerably sharper than most other places, thus most dock tanks had only four coupled (i.e. driving) wheels in order to allow them to negotiate the tight curves.

==Design==
With the growth in freight transport a more powerful engine was required, resulting in this design by [[Henry Fowler (engineer)|Sir Henry Fowler]]: an {{whyte|0-6-0|T}} locomotive with a {{convert|9|ft|6|in|m|2|adj=on}} wheelbase which, aided by the use of [[Cartazzi axle|Cartazzi self-centring axlebox]]es on the rear axle, allowed the engines to negotiate curves of {{cvt|2+1/2|ch|m ft|0}}.<ref name="RM" >{{cite magazine

==Construction==
Ten members of the class were built on Lot 61 in 1928 and 1929 by [[Derby Works]], although unusually for dock tanks they incorporated outside cylinders which was normally considered too dangerous in an area where people were working close to the track.<ref name="RM" /> Other than this they were typical of most dock tanks with simple slide valves and oval buffers.

==Numbering==
They were initially numbered 11270–11279, renumbered under the [[LMS locomotive numbering and classification#1932 Renumbering|LMS 1933 renumbering scheme]] to 7100–7109, and renumbered again in 1939 to 7160–7169. Despite the small class size, the LMS considered them standard locomotives. After nationalisation in 1948, [[British Rail]]ways added 40000 to their numbers making them 47160–47169, and allocated half the class to Scottish depots<ref name="RM" /> for use on branch lines as well as docks.

==Withdrawal==
Withdrawals took place between 1959 and 1964 with all examples being scrapped.
