Henry Hoy

Henry Albert Hoy (1855–1910) was a locomotive engineer with the Lancashire and Yorkshire Railway (L&YR).

In 1872 he began an apprenticeship under Francis William Webb at the London and North Western Railway's Crewe works.

In 1884 Hoy moved to the L&YR, becoming an outdoor assistant in the locomotive department under Barton Wright in Manchester; he was promoted to works manager a year later.

His principal contribution was the design of an electrification system for the Liverpool to Southport line, including motor bogies.

In the worst of these, a fatal boiler explosion with a Class 30 0-8-0 near Knottingley in 1901 was caused by the failure of a number of firebox rod stays made from this alloy.

[1][2] The size of the firebox waterspace was also criticised, although this was due to Aspinall's standard boilers, rather than Hoy's construction.
