Whyte notation
The Whyte notation for classifying steam locomotives by wheel arrangement was devised by Frederick Methvan Whyte, and came into use in the early twentieth century following a December 1900 editorial in "American Engineer and Railroad Journal". The notation counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, groups of numbers being separated by dashes. Other classification schemes, like UIC classification and the French, Turkish and Swiss systems for steam locomotives, count axles rather than wheels.
Burmese kyat
In 1952, the Union Bank of Burma formed a Currency Board which took over control of the issuing of currency and a more important change to the currency was the introduction of the decimal system in which 1 kyat was decimalised into 100 pyas. On 12 February 1958, the Union Bank of Burma introduced the first kyat notes, in denominations of 1, 5, 10 and 100 kyats. These were very similar in design to the last series of rupee notes, issued earlier. Later on, 21 August 1958, 20 and 50 kyats notes were introduced. The 50 and 100 kyat notes were demonetised on 15 May 1964. This was the first of several demonetisations, ostensibly carried out with the aim of fighting black marketeering.
