My vector drawing (no auto trace/copy) of the Mallard, significant for being the holder of the official world speed record for steam locomotives.
Number 4468 Mallard is a London and North Eastern Railway Class A4 4-6-2 Pacific steam locomotive built at Doncaster, England in 1938.
The A4 class was designed by Sir Nigel Gresley as an express locomotive type to power high-speed streamlined trains. The wind-tunnel-tested, aerodynamic body and high power allowed the class to reach speeds of over 100 miles per hour (160 km/h), though in everyday service it was relatively uncommon for any steam hauled service in the UK to exceed 90 mph. Mallard was in service until 1963, when it was retired, having covered almost one and a half million miles (2.4 million km).
