LMS Sentinel 7164

LMS Sentinel number 7164 was a small shunting steam locomotive built in 1931 by Sentinel Waggon Works as works number 8593 and taken into London, Midland and Scottish Railway stock in 1932. It was a single-speed Sentinel with a vertical boiler and geared steam motor, and the only LMS example of the early BE or Balanced Engine design, which placed the boiler and engine at opposite ends of the frames with the water tank in the centre, unlike the later Central Engine design of 7160 to 7163. It was the smallest of the four Sentinel classes the LMS used and was classified 0F. Renumbered 7184 in 1939 and 47184 under British Railways, it was withdrawn in 1955 from Crewe Works and scrapped. A similar Sentinel, 7232 Ann, was painted as 7164 on the Embsay and Bolton Abbey Steam Railway in 2003.
