History


With the advent of the railways in the early nineteenth century, a need arose for a specialized group of engineer
Engineer
An engineer is a professional practitioner of engineering, concerned with applying scientific knowledge, mathematics and ingenuity to develop solutions for technical problems. Engineers design materials, structures, machines and systems while considering the limitations imposed by practicality,...

s capable of dealing with the unique problems associated with Railway engineering. As the railways expanded and became a major economic force, a great many engineers became involved in the field, probably the most notable being Richard Trevithick
Richard Trevithick
Richard Trevithick was a British inventor and mining engineer from Cornwall. His most significant success was the high pressure steam engine and he also built the first full-scale working railway steam locomotive...
