The '''Oldenburg G 4.2''' [[steam locomotives]] were [[goods train]] engines built for the [[Grand Duchy of Oldenburg State Railways]] (''Großherzoglich Oldenburgische Staatseisenbahnen'') between 1895 and 1909 in several series.  

== History ==
They were [[compound locomotives]] manufactured by [[Hanomag]] based on a [[Prussian state railways|Prussian]] design, the [[Prussian G 4.2]]. Of the total of 27 examples, 19 were to have been taken over in 1923 by the [[Deutsche Reichsbahn-Gesellschaft|Deutsche Reichsbahn]] as '''DRG class 53.10''' with numbers 53 1001–1011 and 53 1051–1058. In the 1925 [[DRG renumbering plan for steam locomotives]], however, only eleven engines were listed: numbers 53 1001–1003 and 53 1051–1058. Numbers 53 1001 and 1002 (previously 53 1004 and 1005) came from the first series, number 53 1003 (previously 53 1011) from the second and 53 1051-1058 from the third.<ref>{{cite web|title=Lokomotivdatenbank|periodical=Beiträge zur Lokomotiv- und Eisenbahngeschichte|url=http://www.beitraege.lokomotive.de/datenbank/d_datenbank.php|accessdate=2016-06-18|last=Ingo Hütter|language=German|archive-date=2019-09-06|archive-url=https://web.archive.org/web/20190906090700/http://www.beitraege.lokomotive.de/datenbank/d_datenbank.php|url-status=dead}}</ref>{{sfnb|Hütter|2012|p=421}}

== Description ==
The first vehicles were equipped with an outside valve gear of the [[Allan valve gear|Allan]] type. The 15 engines delivered from 1907 had an outside [[Walschaerts valve gear]]. The latter were also fitted with a ''Ranafier'' steam dryer and a [[steam dome]].

On a line with a 0.5% incline, the engines attained a speed of 30&nbsp;km/h when hauling a 500 tonne train.
