Editing 4-8-2 (section)

===Czechoslovakia===
The [[Czechoslovak State Railways]] (ČSD) introduced the 498.0 class {{nowrap|4-8-2}} express passenger locomotive in 1938 following successful trials in the [[Tatra Mountains]] comparing it to an alternative [[2-8-4]] Berkshire prototype. In 1954, the design was developed further into the 498.1 class. These technically sophisticated locomotives were reputedly capable of 11% [[thermal efficiency]].<ref>{{cite web |url=http://home.c2i.net/schaefer/csd/index.html |archive-url=https://archive.today/20080302102158/http://home.c2i.net/schaefer/csd/index.html |url-status=dead |archive-date=2008-03-02 |title=Steam locomotives of the former Czechoslovakian Railway (CSD)|author=Schaefer, Hans |access-date=2008-02-08|date=October 2006}}</ref>
