Lokomotif uap: Perbedaan antara revisi

Lokomotif uap pertama yang bisa dijalankan menggunakan lebar sepur {{RailGauge|3ft}}. Namanya adalah ''Coalbrookdale Locomotive'', yang dibuat oleh Trevithick pada 1802. Loko ini dibuat di pabrik besi [[Coalbrookdale]] di [[Shropshire]], [[Britania Raya]] meski tak ada catatan pengoperasian yang bertahan.<ref>{{cite book |title=Life of Richard Trevithick: With an Account of His Inventions, Volume 1 |author=Francis Trevithick |publisher=E.&F.N.Spon |date=1872}}</ref> Pada 21 Februari 1804, perjalanan kereta api uap pertama telah dilaksanakan menggunakan lokomotif uap rancangan Trevithick lainnya pada jalur trem dari pabrik besi [[Pen-y-darren]] dekat [[Merthyr Tydfil]], menuju [[Abercynon]] di South Wales dengan sepur {{RailGauge|4ft4in}}.<ref>{{cite web |url=http://www.museumwales.ac.uk/en/rhagor/article/trevithic_loco/ |title=Richard Trevithick's steam locomotive &#124; Rhagor |publisher=Museumwales.ac.uk |accessdate=2009-11-03 |url-status=dead |archiveurl=https://web.archive.org/web/20110415125004/http://www.museumwales.ac.uk/en/rhagor/article/trevithic_loco |archivedate=15 April 2011 |df=dmy-all }}</ref><ref>{{cite news | title = Steam train anniversary begins | url = http://news.bbc.co.uk/1/hi/wales/3509961.stm | publisher = [[BBC]] | accessdate = 2009-06-13 | quote = A south Wales town has begun months of celebrations to mark the 200th anniversary of the invention of the steam locomotive.
