Prussian State 0-4-2 Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class G2 (Locobase 6346)

Data from Christian Lindecke data from [link] (14 November 2004). This is an unusual wheel arrangement for a "goods" locomotive.


Class T 2 (Locobase 6349)

Data from Christian Lindecke data from [link] (14 November 2004); and "Preuáische T 2" in Wikipedia at [link], last accessed 3 October 2023. Two builders were Henschel & Sohn, and Cassel.

Wikipedia's entry says the design shunted at large and medium-sized stations. (Locobase supposes this means most of its work was making up trains of passenger carriages.).

But the T2 designation included several variants from which Locobase extracted the Berliner's data. Wikipedia said this variant operated on a variety of traffic service in the city, the ring roads, and suburban railways. An exhaust steam condenser lay between the cylinders.

The last Berliner T2 was retired in 1916.


Class T 2 /84 (Locobase 6350)

Data from Christian Lindecke data from [link] (14 Nov 2004). A few years after the first 70 T2s went into service, another group of 18 with smaller drivers were delivered. Factor of adhesion fell and the boiler and firebox were enlarged.


Class T4 2 / BR 69 70 (Locobase 6348)

Data from Christian Lindecke data from [link] (14 Nov 2004).

A rare arrangement for a tank locomotive. Although this class also received a DRG class ID, it's likely that none of the class actually entered the national railway's service.
