General Sir Frederick Alfred Pile, 2nd Baronet, GCB, DSO, MC (14 September 1884 – 14 November 1976) was a senior British Army officer who served in both World Wars.

His youngest brother, Cyril John Pile, served in the Royal Flying Corps during the First World War, and was killed in action in 1917.

[3] He was married in 1915, thrice mentioned in dispatches, and awarded both the Military Cross[6] and the Distinguished Service Order[7] during the war.

Even before the war started, he foresaw the likely pressures on personnel and investigated whether women would be capable to taking a part in anti-aircraft batteries.

Alan Brooke who replaced Dill said that "Tim" Pile had certain valuable qualities but he could not think of a worse selection as CIGS.

[15] In 1948, a locomotive of the Southern Railway SR Battle of Britain Class was named after Pile at Waterloo station in London.

[16][17] After residing at Woodham Brothers scrapyard in Barry, South Wales it was initially preserved at the Avon Valley Railway for many years, and then moved to the Watercress Line in 2011.
