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.
Chris Whyte
Whyte returned to the top flight in 1990, when he was signed for £450,000 by Howard Wilkinson's Leeds United. He was nearly ever-present for the next three seasons, putting in 146 appearances as Leeds won the 1991–92 First Division title. In 1993, he moved to Birmingham City, winning the 1994–95 Second Division title with the Blues. After a brief spell at Coventry City on loan, Whyte left Birmingham in 1996, and subsequently played for Charlton Athletic, Leyton Orient, Oxford United and Rushden & Diamonds.
